+'df' returns 0: Free disk space is distributed among the volumes in
+NetWare. df is only able to report one number per mounted
+filesystem. As connections are quite expensive for NetWare (with
+mars_nwe and lwared that might change ...), I rejected the alternative

+I only began this file with ncpfs-0.12. If you're interested in older
+versions, you can find them on ftp.gwdg.de:/pub/linux/misc/ncpfs/old.
+
+ncpfs-0.20 -> ncpfs-0.21
+- Included two bugfixes in ncplib.c found by Jeff Buhrt
+  <buhrt@iquest.net>.
+- Included a bugfix in kernel code that could only show for servers
+  that do not support namespace calls. I should have tried ncpfs
+  against lwared... Thanks to Neil Turton <ndt1001@chu.cam.ac.uk> for
+  this fix.
+
+ncpfs-0.19 -> ncpfs-0.20
+- Changed the home site for ncpfs from linux01.gwdg.de:/pub/ncpfs
+  to ftp.gwdg.de:/pub/linux/misc/ncpfs. linux01 will remain available,
+  but we would like to reduce the load on that machine. Sites
+  mirroring linux01 please redirect your mirror software to
+  ftp.gwdg.de. Thanks.
+- Removed a bug in ncplib.c that made slist require a full
+  login. Thanks to Neil Turton <ndt1001@chu.cam.ac.uk> for the hint.
+- The first real user contribution: ncopy by Brian G. Reid
+  (breid@tim.com) and Tom C. Henderson (thenderson@tim.com). Many
+  thanks to you! If you find bugs in ncopy, tell them, not me ;-)
+- Handle expired passwords. Thanks to "Mathew Lim" <M.Lim@sp.ac.sg>
+  for the hint.
+
+ncpfs-0.18 -> ncpfs-0.19
+
+- hacked around in ncplib.[ch] quite heavily.
+- SAP handling in ipxparse.c. Thanks to Jeff Buhrt <buhrt@iquest.net>
+- Changed error handling to use the com_err library. This should
+  eventually provide better error messages, because it's now much
+  easier to define nice messages.
+- If no server is active, report this correctly
+- added nsend
+
+ncpfs-0.17 -> ncpfs-0.18
+
+- Another attempt at solving the problem that -n is not working.
+- Forgot nprint in 0.17 util/Makefile.
+- nprint left connections open when it fails
+- added options -r and -t to ncpmount to tune ncpfs connections.
+
+ncpfs-0.16 -> ncpfs-0.17
+
+- Changed the name of fsinfo to nwfsinfo, to avoid a name clash with
+  the X windows utility. Thanks to Henning Brockfeld
+  <Henning.Brockfeld@lrz.uni-muenchen.de> for this hint. (still
+  waiting for your scripts.. :-))
+- made nwmsg available. This enables you to receive NetWare user
+  broadcast messages. Please note that you need at least kernel 1.3.68
+  for this feature.
+- pserver now prints debugging output via syslog().
+- Included ipxdump, a nice little utility, that has helped some
+  people.
+
+- And now the big one: you can re-export ncpfs-mounted directories
+  with nfsd! You have to mount single volumes by specifying -V volume
+  to ncpmount, and call nfsd and mountd with the option --re-export.  
+  See the manual page of ncpmount for more information. Please note
+  that I will send Linus the required patch on 1. March 1996, so you
+  will have to use kernel 1.2.13 or wait at least for 1.3.70.
+
+ncpfs-0.15 -> ncpfs-0.16
+
+- Included ipx-1.0, made available by Greg Page <greg@caldera.com>,
+  Caldera
+- Made -n work for password-less accounts. Thanks to Alexander Jolk
+  <jolk@ap-pc513b.physik.uni-karlsruhe.de>.
+- Fixed the kerneld support.
+- Fixed the NetWare 4.1 problem. Many thanks to
+  Chatchai JANTARAPRIM <chat@ratree.psu.ac.th> and 
+  hitesh.soneji@industry.net for their patience.
+
+ncpfs-0.14 -> ncpfs-0.15

FAQ

@@ -0,0 +1,41 @@
+There is certainly not enough material to call this an FAQ, but some
+questions reach me regularly. Probably the documenation is not clear
+enough.
+
+-------------------------------------------------------------------------------
+
+Q: Does ncpfs support long file names, using the OS/2 namespace?
+
+No. Not yet. I still have to sort out how that really works. But it should
+certainly be possible.
+
+-------------------------------------------------------------------------------
+
+Q: When I re-export ncpfs-mounted directories via nfs, I get messages like
+   'pwd: cannot get current directory', and other strange things happen to
+   the nfs clients. What's wrong?
+
+When you want to export a directory via NFS, you have to do two things:
+
+- You have to invoke mountd and nfsd with the option --re-export. On my
+  computer, both are invoked at system startup from the file
+  /etc/rc.d/rc.inet2.
+
+- You can not export a complete NetWare server hierarchy with all volumes
+  under a single mount point. You have to mount a single server volume to
+  make it re-exportable. Invoke ncpmount with the option -V volume to do
+  this.
+
+-------------------------------------------------------------------------------
+
+Q: When I compile ncpfs, I get a message like the following:
+
+make[1]: Entering directory `/home/me/netware/ncpfs/kernel-1.2/src'

-This is version 0.1 of ncpfs, a free NetWare client for Linux. For me
-it works with 1.3.32 and 1.3.35.
+This is ncpfs, a free NetWare client filesystem for Linux. Besides
+some little utilities it also contains nprint, which enables you to
+print on NetWare print queues. The opposite side, pserver, is also
+provided.
 
-I know that this piece of software is VERY incomplete, as it only
-gives you read-only access. I have to apologize for that. But I
-thought I should make it publically available, because I have tried to
-ask several people about the legal status of the code. I did not get
-very satisfying answers. So I publish ncpfs to open it for
-criticism. If nobody complains, I will go on working.
+INSTALLATION
 
-To install ncpfs, just type 'make', 'insmod ncpfs.o' and 
-'ncpmount server mount-point user password'. Please note that your IPX
-system has to be configured correctly. There has to be a route to the
-internal network of your server. I use tools from the dosemu-0.60.3
-distribution to do this. Once again I have to apologize for this
-cryptic description, but before I'm sure that I'm allowed to do all
-this I will not do more.
+The installation of ncpfs depends on the kernel version you are
+using. For kernel 1.2, you should simply type 'make' and look at
+what's in the bin/ directory after that. Please be sure that your
+kernel resides in /usr/src/linux, because the file
+kernel-1.2/src/sock.c has to refer directly to it.
+
+If you use Kernel 1.3, please be sure that you use at least
+1.3.71. ncpfs does NOT work with any earlier 1.3.x kernel.
+
+If you use Kernel 1.3.71 or later, you might have to recompile your
+kernel. With these kernels, the kernel part of ncpfs is already
+included in the main source tree. If you want to use ncpfs, you should
+say 'y' to 'make config' when you are asked for IPX, and again when it
+asks for ncpfs. After you have rebooted with the new kernel, 'cat
+/proc/filesystems' should show you a line saying that the kernel knows
+ncpfs.
+
+With Kernel 1.3.71 or later you also have to modify the Makefile in the
+directory you found this README in. Please see the Makefile for the
+necessary modifications. Then typing 'make' should work with no
+problem.

-Subject: legal status of your source code?
+USING NCPFS
+
+Please note that your IPX system has to be configured correctly. If
+you want to take the 'Plug-and-Play' route, you can simply say
+'ipx_configure --auto_interface=on --auto_primary=on'. If ncpmount
+does not work immediately, you should wait for about 1 minute and try
+again. In that period, an IPX packet should have passed by and your
+network interface should have configured itself automatically.
+
+If all that does not work and you want to do the configuration by
+hand, note that there has to be a route to the internal network of
+your server. Please see the file util/start_ipx for an example.
+
+I use tools written by Greg Page, Caldera. I hope I did not do too
+much harm to their business. For your convenience I included the
+contents of the file ipx.tar made available by Caldera.
+
+My main source of information is a book written in german by Manfred
+Hill and Ralf Zessin, "Netzwerkprogrammierung in C", IWT Verlag GmbH,
+1995, ISBN 3-88322-491-X. It contains quite a lot of typographical and
+other errors, but I find it very valuable as an introduction to NCP
+programming. If you know about the concepts and possibilities of NCP,
+Ralph Brown's interrupt list becomes much more readable. It's much
+easier to find undocumented information if you know what to look for!
+
+For the curious: the files ncplib.[ch] are a library that makes it
+possible to send NCP requests to the server over a mounted
+directory. I use it to keep the encryption stuff out of the kernel by
+logging in from user space. Look at the file ncptest.c for other
+possible uses. I use ncptest to check my assumptions about the widely
+undocumented NetWare Core Protocol.  Maybe this is the beginning of a
+free NetWare API for Linux! I would be happy to receive your comments
+on this.
 
 
-Hello!
+THANKS
 
-I hope that you're the right one to write to, you are the first on your WWW
-server. If you are not, could you please forward this message to the right
-person? Thanks.
+I do not want to leave those unmentioned, who have helped me with
+ncpfs. 
 
-I'm currently exploring the possibility to write a free (in the GNU GPL
-sense) NCP filesystem, which would allow me to access a novell server
-transparently. For that I would like to use the encryption functions you
-published in DDJ 11/93, Undocumented Corner. I would make some cosmetic
-changes, such as other indentations, minor code changes and so on. But I do
-not know if that allows me to publish this code under GPL. One alternative
-would be to publish a diff against your listing, but that would probably
-contain much of your code as well, and it would be very inconvenient for
-the average user.
+The most enthusiastic user and tester is certainly Uwe Bonnes
+<bon@elektron.ikp.physik.th-darmstadt.de>. So far he's the only one
+who has contributed something, namely manpages and corretions to
+existing manpages.
 
-I think that you have some kind of standard procedure for such a
-case. Please tell me what I should do.
+Ales Dyrak has written lwared, which was the initial start for ncpfs.
 
-Many thanks in advance,
+Alan Cox has found some bugs I would probably never have found.

+LIMITATIONS (compare these with smbfs :-)
 
+The limitations ncpfs has are the natural limitations of the NCP
+protocol, which was designed with MS-DOS based PCs in mind. The first
+limitation is the lack of uid, gid and permission information per
+file. You have to assign those values once for a complete mounted
+directory.
 
+You will not be able to access servers that require packet
+signatures. This seems to be one of Novell's bigger secrets :-(.
 
+Have fun with ncpfs!

+Here's a list of things I want to do. Feel free to send suggestions,

+
+- Add flags to pserver's command line, so that the print command can

+- do rtt estimation, like tcp does.

+- Do better connection management. I imagine to create a ncpd.

+- When ncp is done, one can think about mounting several volumes over

+This file contains a very short introduction to the IPX implementation
+on Linux.  Feel free to forward comments (especially suggested additions)
+to greg@caldera.com.
+
+The following are important definitions in understanding the descriptions
+in this README file.
+
+IPX Interface - This is the item to which IPX sockets are bound.
+An IPX interface corresponds to an IPX Network Number which corresponds 
+to a physical device and frame type.  A sample IPX Interface would be:
+Network Number: 0x00ABCDEF
+Device: Eth0 
+Frame Type: 802.2.
+The particular interface is selected during binding by using the
+Network Number (see sample code below).
+
+Primary Interface - The interface that is selected by default when
+binding a socket.  This is selected when binding by using
+a network number of 0 (see sample code below).
+
+Internal Network - This is a special kind of IPX interface that does
+not have a physical device or frame type.  It is used to provide
+a route-independent address for service providers.   Internal network
+numbers are optional; however, when one is present it is also the
+Primary Interface.
+
+This tar file contains the following IPX utilities:
+
+ipx_interface.c
+This program is used to create an IPX interface.  
+
+ipx_internal_net.c
+This program is used to create an IPX Internal Network number.  
+
+ipx_route.c
+This program creates an IPX route.
+
+ipx_configure.c
+This program is used to read/write two configuration parameters:
+	AUTO INTERFACE CREATE - IPX should/shouldn't automatically create
+		an IPX interface when it discovers one that has not been
+		registered via ipx_interface above.
+	AUTO PRIMARY SELECT - IPX should/shouldn't automatically select
+		a primary interface when it one an interface exists and
+		none are designated as the primary.  Manual designation
+		is performed via ipx_interface.
+
+By default, these are both turned off.
+				
+The following are sample IPX programs (found in directory Samples):
+
+ipxrcv.c and ipxsend.c 
+ipxsend will send a single packet to an instance of ipxrcv running on the 
+same machine.  It uses getsockname(2) to determine the address to which to 
+send the packet.  
+rip.c
+rip passively monitors the rip traffic on the attached IPX network.
+sap.c
+sap passively monitors the sap traffic on the attached IPX network.
+
+There are three files in /proc/net that relate to IPX.
+ipx_interface contains the list of IPX interfaces.
+ipx_route contains the list of IPX routes.
+ipx contains the list of IPX sockets in use.

+This is a VERY stupid packet sniffer for IPX ethernet packets.
+
+ =============================================
+ ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

+ =============================================
+
+If you are using unencrypted passwords, and use this tool to send a
+dump to somebody else or store it on a computer, you might very well
+store passwords there. So, be VERY careful! This is exactly the kind
+of tools Novell designed the encrypted passwords for (or against).
+
+
+
+I hacked it together to be able to help people with problems with
+ncpfs. The socket handling was taken from Statnet-2.0.
+
+You can use it to watch commercial NetWare clients when they talk to
+servers. I divided the program into 2 parts, ipxdump and ipxparse.
+
+ipxdump simply pumps all the IPX frames it receives to stdout.
+
+If you use ipxdump to watch a workstation, you can use the simple
+filter function ipxdump provides. You can call ipxdump with the node
+address of the workstation you want to watch. This way only the
+packets this workstation sends and receives are monitored. As an
+example, I call ipxdump as
+
+  ./ipxdump 00001B038B11
+
+to look at my 286/10MHz test 'workstation'. ipxdump still generates
+huge amounts of data, so you should be very careful to start it just
+before you perform the operation (such as file creation for OS/2
+clients with NW4.1 as a server, or a 'dir' on a directory with long
+and short file names, or an encrypted password change ;-)) and stop it
+directly after that. And, please gzip -9 and uuencode it before you
+send it to anybody.
+
+ipxparse will eventually take apart the dump that ipxdump
+generates. They can as well be used in a pipe. Currently ipxparse does
+not do anything sensible, but that will definitely change.

+mount-point
+
+.SH DESCRIPTION
+This program is used to mount all volumes of the specified NetWare Fileserver
+under the specified mount point.
+
+.B ncpfs
+is a linux filesystem which understands the NCP protocol. This is the
+protocol Novell NetWare clients use to talk to NetWare servers. ncpfs
+was inspired by
+.B lwared,
+a free NetWare emulator for Linux written by Ales Dryak. See
+ftp://klokan.sh.cvut.cz/pub/linux for this very intersting program.
+
+.B ncpmount
+when invoked with all appropriate arguments attaches, logs in and
+mounts all of the volumes associated with the specified fileserver that are
+readable by the user id under the specified mount point.
+.B ncpmount
+when invoked without any arguments specifying the fileserver, user id and
+password checks the file
+.I $HOME/.nwclient
+to find a file server, a user name and possibly a password to use for the
+specified mount point. See nwclient(5) for more information. Please note
+that the access permissions of .nwclient MUST be 600, for security reasons.
+
+.SH OPTIONS
+.B mount-point
+.RS 3
+.B mount-point
+is the directory you want to mount the filesystem over. Its function is the
+the same as for a normal mount command.
+
+If the real uid of the caller is not root,
+.B ncpmount
+checks whether the user is allowed to mount a filesystem on the
+mount-point. So it should be safe to make 
+.B ncpmount
+ setuid root. The filesystem stores the uid of the user who called
+ncpmount. So
+.B ncpumount
+can check whether the caller is allowed to unmount the filesystem.
+.RE
+
+.B -S
+.I server
+.RS 3
+.B server
+is the name of the server you want to use.
+.RE
+
+.B -h
+.RS 3
+.B -h
+is used to print out a short help text.
+.RE
+
+.B -C
+.RS 3
+By default passwords are converted to uppercase before they are sent
+to the server because most servers require this. This option disables this
+feature ensuring that passwords are sent without any case conversion.
+.RE
+
+.B -n
+.RS 3
+.B -n
+must be specified for logins that do not have a password configured.
+.RE
+
+.B -P
+.I password
+.RS 3
+specifies the password to use for the Netware user id.
+
+If neither
+.B -n
+nor the
+.B -P
+arguments are specified ncpmount will prompt for a password. This
+makes it difficult to use in scripts such as /etc/rc. If you want to
+have ncpmount work automatically from a script you must include the
+appropriate option and be very careful to ensure that appopriate file
+permissions are set for the script that includes your password to
+ensure that others can not read it.
+.RE
+
+.B -U
+.I user name
+.RS 3
+Specifies the Netware user id to use when logging in to the fileserver. If
+this option is not specified then ncpmount will attempt to login to the
+fileserver using the Linux login id of the user invoking ncpmount.
+.RE
+
+.B -u
+.I uid,
+.B -g
+.I gid
+.RS 3
+ncpmount does not yet implement a scheme for mapping NetWare users/groups
+to Linux users/groups. Linux requires that each file has an owner and group id.
+With
+.B -u
+and
+.B -g
+you can tell ncpmount which id's it should assign to the files in the
+mounted directory.
+
+The defaults for these values are the current uid and gid.
+.RE
+
+.B -c
+.I user name
+.RS 3
+.B -c
+names the user who is the 
+.I owner
+of the connection, where owner does not refer to file ownership (that
+"owner" is set by the -u argument), but the owner of the mount, ie: who
+is allowed to call ncpumount on this mount. The default owner of the
+connection and the mount is the user who called ncpmount. This option
+allows you to specify that some other user should be set as the owner.
+
+In this this way it is possible to mount a public read-only directory,
+but to allow the lp daemon to print on NetWare queues. This is
+possible because only users who have write permissions on a directory
+may issue ncp requests over a connection. The exception to this rule
+is the 'mount owner', who is also granted 'request permission'.
+.RE
+
+.B -f
+.I file mode,
+.B -d
+.I dir mode
+.RS 3
+Like 
+.B -u
+and
+.B -g,
+these options are used to determine what permissions should be assigned
+files and directories of the mounted volumes. The values must be specified
+as octal numbers. The default values are taken from the current umask, where
+the file mode is the current umask, and the dir mode adds execute permissions
+where the file mode gives read permissions.
+
+Note that these permissions can differ from the rights the server
+gives to us. If you do not have write permissions on the server, you
+can very well choose a file mode that tells that you have. This
+certainly cannot override the restrictions imposed by the server.
+.RE
+
+.B -V
+.I volume
+.RS 3
+There are 2 general ways you can mount a NetWare server's disk space:
+Either you can mount all volumes under one directory, or you can mount
+only a single volume.
+
+When you choose to mount the complete disk space at once, you have the
+advantage that only one Linux mount point and only one
+NetWare connection is used for all the volumes of this server. Both of
+these are limited resources. (Although raising the number of Linux
+mount points is significantly cheaper than raising the number of
+available NetWare connections ;-))
+
+When you specify to mount a single volume by using the option
+.B -V
+.I volume,
+you have the big advantage that nfsd is able to re-export this mounted
+directory. You must invoke 
+.B nfsd
+and
+.B mountd
+with the option
+.I --re-export
+to make nfsd re-export ncpfs mounted directories. This uses one Linux
+mount point and one NetWare connection per mounted volume. Maybe
+sometime in the future I will make it possible to mount all volumes on
+different mount points, using only one connection.
+.RE
+
+.B -t
+.I time_out
+.RS 3
+With 
+.B -t
+you can adjust the time ncpfs waits for the server to answer a request
+it sent. Use the option to raise the timeout value when your ncpfs
+connections seem to be unstable although your servers are well
+up. This can happen when you have very busy servers, or servers that
+are very far away.
+
+.I time_out
+is specified in 1/100s, the current default value is 60.
+.RE
+
+.B -r
+.I retry_count
+.RS 3
+As 
+.B -t, -r
+can be used to tune the ncpfs connection to the server. With
+retry_count you can specify how many times ncpfs will attempt to send
+a packet to the server before it decides the connection is dead. The
+current default value is 5.
+
+Currently ncpfs is not too clever when trying to find out that
+connections are dead. If anybody knows how to do that correctly, as it
+is done by commercial workstations, please tell me.
+.RE
+
+.B -v
+.RS 3
+Print ncpfs version number
+.RE
+
+.SH NOTES
+You must configure the IPX subsystem before ncpmount will work.
+It is especially important that there is a route to the internal network
+of your server.
+
+.SH ENVIRONMENT VARIABLES
+.B USER / LOGNAME
+.RS 3
+The variables USER or LOGNAME may contain the username of the person
+using the client.  USER is tried first. If it's emtpy, LOGNAME is
+tried.
+.RE
+
+.SH DIAGNOSTICS
+

+.TH NWCLIENT 5 12/27/1995 nwmount nwmount
+.SH NAME
+nwclient \- configuration file for NWClient program suite
+.SH DESCRIPTION
+This manual page describes the rather simple format of the file
+.B $HOME/.nwclient,
+the configuration file for the NWClient program suite.
+.SH FILE FORMAT
+The file 
+.B $HOME/.nwclient
+consists of several lines, each describing a NWClient
+connection. Lines beginning with # and empty lines are ignored as
+comments.
+
+Because you can store passwords in .nwclient, the user programs will
+only scan .nwclient when only the file owner has access rights to
+the file. The file must be have permissions 0600.
+
+To specify a NWClient connection, the name of the file server, the
+user name to be used and a password is necessary. The server name and
+the user name are specified as SERVER/USER, and the password is
+separated by a blank. The password field can be omitted. In this case
+the user programs will ask you for a password. If you specify the
+password to be just a dash, then no password is used.
+
+The first valid specification has a special meaning: If the user does
+not name a server on the command line, the first specification is used
+as a 'preferred connection'.
+
+An example might be the following:
+
+   # The preferred connection, the user is asked
+   # for a password
+   FS311/ME
+   # And a passwordless account on another server 
+   CD-SERV/GUEST -
+
+With these lines in $HOME/.nwclient, calling 'nwmount /mnt' will mount
+the the file server FS311 with user name ME on /mnt after asking the
+user for a password.
+
+\'nwmount -S cd-serv /cd' will silently mount the server cd-serv on /cd.
+
+.B nprint
+,
+.B pqlist
+and other user programs that require a valid login also look up
+.I $HOME/.nwclient
+to find a file server, a user name and possibly a password. 
+
+Please note that the access permissions of .nwclient MUST be 600, for
+security reasons.

+.SH NAME
+nwmsg \- Deliver NetWare user broadcast messages
+.SH SYNOPSIS
+.B nwmsg
+.I mount-point
+.SH DESCRIPTION
+.B nwmsg
+is called by kerneld when a broadcast message arrives from a NetWare
+server.
+.B nwmsg
+fetches this message via the mount point and delivers it to
+the user using the same way write(1) uses. 
+
+Please note that 
+.I kerneld
+must run when broadcast messages should be delivered to users.
+
+NetWare servers can send asynchronous broadcast messages to users,
+either on explicit request by another user, or when the server is
+shutdown. The client workstation is informed about this event by an
+IPX packet on a special socket, the message socket.
+
+This can happen at any time, so the user has to be informed about this
+event whenever it appears. I chose to use the kerneld feature of the
+Linux kernel to call the program nwmsg. For nwmsg, I used the relevant
+parts of the 
+.I write
+program, so you can expect the NetWare broadcast
+messages to appear where user messages would appear.

+	const char *whoami;
+	long code;
+	const char *format;

+.nf
+.PP
+proc = reset_com_err_hook ();
+.PP
+void initialize_XXXX_error_table ();
+.fi
+.SH DESCRIPTION
+.I Com_err
+displays an error message on the standard error stream
+.I stderr
+(see
+.IR stdio (3S))
+composed of the
+.I whoami
+string, which should specify the program name or some subportion of
+a program, followed by an error message generated from the
+.I code
+value (derived from
+.IR compile_et (1)),
+and a string produced using the
+.I format
+string and any following arguments, in the same style as
+.IR fprintf (3).
+
+The behavior of
+.I com_err
+can be modified using
+.I set_com_err_hook;
+this defines a procedure which is called with the arguments passed to
+.I com_err,
+instead of the default internal procedure which sends the formatted
+text to error output.  Thus the error messages from a program can all
+easily be diverted to another form of diagnostic logging, such as
+.IR syslog (3).
+.I Reset_com_err_hook
+may be used to restore the behavior of
+.I com_err
+to its default form.  Both procedures return the previous ``hook''
+value.  These ``hook'' procedures must have the declaration given for
+.I proc
+above in the synopsis.
+
+The
+.I initialize_XXXX_error_table
+routine is generated mechanically by
+.IR compile_et (1)
+from a source file containing names and associated strings.  Each
+table has a name of up to four characters, which is used in place of
+the
+.B XXXX
+in the name of the routine.  These routines should be called before
+any of the corresponding error codes are used, so that the
+.I com_err
+library will recognize error codes from these tables when they are
+used.
+
+The
+.B com_err.h
+header file should be included in any source file that uses routines
+from the
+.I com_err
+library; executable files must be linked using
+.I ``-lcom_err''
+in order to cause the
+.I com_err
+library to be included.
+
+.\" .IR for manual entries
+.\" .PP for paragraph breaks
+
+.SH "SEE ALSO"
+compile_et (1), syslog (3).

+
+UNIX has always had a clean and simple system call interface, with a
+standard set of error codes passed between the kernel and user
+programs.  Unfortunately, the same cannot be said of many of the
+libraries layered on top of the primitives provided by the kernel.
+Typically, each one has used a different style of indicating errors to
+their callers, leading to a total hodgepodge of error handling, and
+considerable amounts of work for the programmer.  This paper describes
+a library and associated utilities which allows a more uniform way for
+libraries to return errors to their callers, and for programs to
+describe errors and exceptional conditions to their users.

+@section Why com_err?
+
+In building application software packages, a programmer often has to
+deal with a number of libraries, each of which can use a different
+error-reporting mechanism.  Sometimes one of two values is returned,
+indicating simply SUCCESS or FAILURE, with no description of errors
+encountered.  Sometimes it is an index into a table of text strings,
+where the name of the table used is dependent on the library being
+used when the error is generated; since each table starts numbering at
+0 or 1, additional information as to the source of the error code is
+needed to determine which table to look at.  Sometimes no text messages are
+supplied at all, and the programmer must supply them at any point at which
+he may wish to report error conditions.
+Often, a global variable is assigned some value describing the error, but
+the programmer has to know in each case whether to look at @code{errno},
+@code{h_errno}, the return value from @code{hes_err()}, or whatever other
+variables or routines are specified.
+And what happens if something
+in the procedure of
+examining or reporting the error changes the same variable?
+
+The package we have developed is an attempt to present a common
+error-handling mechanism to manipulate the most common form of error code
+in a fashion that does not have the problems listed above.
+
+A list of up to 256 text messages is supplied to a translator we have
+written, along with the three- to four-character ``name'' of the error
+table.  The library using this error table need only call a routine
+generated from this error-table source to make the table ``known'' to the
+com_err library, and any error code the library generates can be converted
+to the corresponding error message.  There is also a default format for
+error codes accidentally returned before making the table known, which is
+of the form @samp{unknown code foo 32}, where @samp{foo} would be the name
+of the table.
+
+@section Error codes
+
+Error codes themselves are 32 bit (signed) integers, of which the high
+order 24 bits are an identifier of which error table the error code is
+from, and the low order 8 bits are a sequential error number within
+the table.  An error code may thus be easily decomposed into its component
+parts.  Only the lowest 32 bits of an error code are considered significant
+on systems which support wider values.
+
+Error table 0 is defined to match the UNIX system call error table
+(@code{sys_errlist}); this allows @code{errno} values to be used directly
+in the library (assuming that @code{errno} is of a type with the same width
+as @t{long}).  Other error table numbers are formed by compacting together
+the first four characters of the error table name.  The mapping between
+characters in the name and numeric values in the error code are defined in
+a system-independent fashion, so that two systems that can pass integral
+values between them can reliably pass error codes without loss of meaning;
+this should work even if the character sets used are not the same.
+(However, if this is to be done, error table 0 should be avoided, since the
+local system call error tables may differ.)
+
+Any variable which is to contain an error code should be declared @t{long}.
+The draft proposed American National Standard for C (as of May, 1988)
+requires that @t{long} variables be at least 32 bits; any system which does
+not support 32-bit @t{long} values cannot make use of this package (nor
+much other software that assumes an ANSI-C environment base) without
+significant effort.
+
+@section Error table source file
+
+The error table source file begins with the declaration of the table name,
+as
+
+@example
+error_table @var{tablename}
+@end example
+
+Individual error codes are
+specified with
+
+@example
+error_code @var{ERROR_NAME}, @var{"text message"}
+@end example
+
+where @samp{ec} can also be used as a short form of @samp{error_code}.  To
+indicate the end of the table, use @samp{end}.  Thus, a (short) sample
+error table might be:
+
+@example
+
+        error_table     dsc
+
+        error_code      DSC_DUP_MTG_NAME,
+                        "Meeting already exists"
+
+        ec              DSC_BAD_PATH,
+                        "A bad meeting pathname was given"
+
+        ec              DSC_BAD_MODES,
+                        "Invalid mode for this access control list"
+
+        end
+
+@end example
+
+@section The error-table compiler
+
+The error table compiler is named @code{compile_et}.  It takes one
+argument, the pathname of a file (ending in @samp{.et}, e.g.,
+@samp{dsc_err.et}) containing an error table source file.  It parses the
+error table, and generates two output files -- a C header file
+(@samp{discuss_err.h}) which contains definitions of the numerical values
+of the error codes defined in the error table, and a C source file which
+should be compiled and linked with the executable.  The header file must be
+included in the source of a module which wishes to reference the error
+codes defined; the object module generated from the C code may be linked in
+to a program which wishes to use the printed forms of the error codes.
+
+This translator accepts a @kbd{-language @var{lang}} argument, which
+determines for which language (or language variant) the output should be
+written.  At the moment, @var{lang} is currently limited to @kbd{ANSI-C}
+and @kbd{K&R-C}, and some abbreviated forms of each.  Eventually, this will
+be extended to include some support for C++.  The default is currently
+@kbd{K&R-C}, though the generated sources will have ANSI-C code
+conditionalized on the symbol @t{__STDC__}.
+
+@section Run-time support routines
+
+Any source file which uses the routines supplied with or produced by the
+com_err package should include the header file @file{<com_err.h>}.  It
+contains declarations and definitions which may be needed on some systems.
+(Some functions cannot be referenced properly without the return type
+declarations in this file.  Some functions may work properly on most
+architectures even without the header file, but relying on this is not
+recommended.)
+
+The run-time support routines and variables provided via this package
+include the following:
+
+@example
+void initialize_@var{xxxx}_error_table (void);
+@end example
+
+One of these routines is built by the error compiler for each error table.
+It makes the @var{xxxx} error table ``known'' to the error reporting
+system.  By convention, this routine should be called in the initialization
+routine of the @var{xxxx} library.  If the library has no initialization
+routine, some combination of routines which form the core of the library
+should ensure that this routine is called.  It is not advised to leave it
+the caller to make this call.
+
+There is no harm in calling this routine more than once.
+
+@example
+#define ERROR_TABLE_BASE_@var{xxxx} @var{nnnnn}L
+@end example
+
+This symbol contains the value of the first error code entry in the
+specified table.
+This rarely needs be used by the
+programmer.
+
+@example
+const char *error_message (long code);
+@end example
+
+This routine returns the character string error message associated
+with @code{code}; if this is associated with an unknown error table, or
+if the code is associated with a known error table but the code is not
+in the table, a string of the form @samp{Unknown code @var{xxxx nn}} is
+returned, where @var{xxxx} is the error table name produced by
+reversing the compaction performed on the error table number implied
+by that error code, and @var{nn} is the offset from that base value.
+
+Although this routine is available for use when needed, its use should be
+left to circumstances which render @code{com_err} (below) unusable.
+
+@example
+void com_err (const char *whoami,  /* module reporting error */
+              long code,           /* error code */
+              const char *format,  /* format for additional detail */
+              ...);                /*  (extra parameters) */
+@end example
+
+This routine provides an alternate way to print error messages to
+standard error; it allows the error message to be passed in as a
+parameter, rather than in an external variable.  @emph{Provide grammatical
+context for ``message.''}
+
+If @var{format} is @code{(char *)NULL}, the formatted message will not be
+printed.  @var{format} may not be omitted.
+
+@example
+#include <stdarg.h>
+
+void com_err_va (const char *whoami,
+                 long code,
+                 const char *format,
+                 va_list args);
+@end example
+
+This routine provides an interface, equivalent to @code{com_err} above,
+which may be used by higher-level variadic functions (functions which
+accept variable numbers of arguments).
+
+@example
+#include <stdarg.h>
+
+void (*set_com_err_hook (void (*proc) ())) ();
+
+void (*@var{proc}) (const char *whoami, long code, va_list args);
+
+void reset_com_err_hook ();
+@end example
+
+These two routines allow a routine to be dynamically substituted for
+@samp{com_err}.  After @samp{set_com_err_hook} has been called,
+calls to @samp{com_err} will turn into calls to the new hook routine.
+@samp{reset_com_err_hook} turns off this hook.  This may intended to
+be used in daemons (to use a routine which calls @var{syslog(3)}), or
+in a window system application (which could pop up a dialogue box).
+
+If a program is to be used in an environment in which simply printing
+messages to the @code{stderr} stream would be inappropriate (such as in a
+daemon program which runs without a terminal attached),
+@code{set_com_err_hook} may be used to redirect output from @code{com_err}.
+The following is an example of an error handler which uses @var{syslog(3)}
+as supplied in BSD 4.3:
+
+@example
+#include <stdio.h>
+#include <stdarg.h>
+#include <syslog.h>
+
+/* extern openlog (const char * name, int logopt, int facility); */
+/* extern syslog (int priority, char * message, ...); */
+
+void hook (const char * whoami, long code,
+           const char * format, va_list args)
+@{
+    char buffer[BUFSIZ];
+    static int initialized = 0;
+    if (!initialized) @{
+        openlog (whoami,
+                 LOG_NOWAIT|LOG_CONS|LOG_PID|LOG_NDELAY,
+                 LOG_DAEMON);
+        initialized = 1;
+    @}
+    vsprintf (buffer, format, args);
+    syslog (LOG_ERR, "%s %s", error_message (code), buffer);
+@}
+@end example
+
+After making the call
+@code{set_com_err_hook (hook);},
+any calls to @code{com_err} will result in messages being sent to the
+@var{syslogd} daemon for logging.
+The name of the program, @samp{whoami}, is supplied to the
+@samp{openlog()} call, and the message is formatted into a buffer and
+passed to @code{syslog}.
+
+Note that since the extra arguments to @code{com_err} are passed by
+reference via the @code{va_list} value @code{args}, the hook routine may
+place any form of interpretation on them, including ignoring them.  For
+consistency, @code{printf}-style interpretation is suggested, via
+@code{vsprintf} (or @code{_doprnt} on BSD systems without full support for
+the ANSI C library).
+
+@section Coding Conventions
+
+The following conventions are just some general stylistic conventions
+to follow when writing robust libraries and programs.  Conventions
+similar to this are generally followed inside the UNIX kernel and most
+routines in the Multics operating system.  In general, a routine
+either succeeds (returning a zero error code, and doing some side
+effects in the process), or it fails, doing minimal side effects; in
+any event, any invariant which the library assumes must be maintained.
+
+In general, it is not in the domain of non user-interface library
+routines to write error messages to the user's terminal, or halt the
+process.  Such forms of ``error handling'' should be reserved for
+failures of internal invariants and consistancy checks only, as it
+provides the user of the library no way to clean up for himself in the
+event of total failure.
+
+Library routines which can fail should be set up to return an error
+code.  This should usually be done as the return value of the
+function; if this is not acceptable, the routine should return a
+``null'' value, and put the error code into a parameter passed by
+reference.
+
+Routines which use the first style of interface can be used from
+user-interface levels of a program as follows:
+
+@example
+@{
+    if ((code = initialize_world(getuid(), random())) != 0) @{
+        com_err("demo", code,
+                "when trying to initialize world");
+        exit(1);
+    @}
+    if ((database = open_database("my_secrets", &code))==NULL) @{
+        com_err("demo", code,
+                "while opening my_secrets");
+        exit(1);
+    @}
+@}
+@end example
+
+A caller which fails to check the return status is in error.  It is
+possible to look for code which ignores error returns by using lint;
+look for error messages of the form ``foobar returns value which is
+sometimes ignored'' or ``foobar returns value which is always
+ignored.''
+
+Since libraries may be built out of other libraries, it is often necessary
+for the success of one routine to depend on another.  When a lower level
+routine returns an error code, the middle level routine has a few possible
+options.  It can simply return the error code to its caller after doing
+some form of cleanup, it can substitute one of its own, or it can take
+corrective action of its own and continue normally.  For instance, a
+library routine which makes a ``connect'' system call to make a network
+connection may reflect the system error code @code{ECONNREFUSED}
+(Connection refused) to its caller, or it may return a ``server not
+available, try again later,'' or it may try a different server.
+
+Cleanup which is typically necessary may include, but not be limited
+to, freeing allocated memory which will not be needed any more,
+unlocking concurrancy locks, dropping reference counts, closing file
+descriptors, or otherwise undoing anything which the procedure did up
+to this point.  When there are a lot of things which can go wrong, it
+is generally good to write one block of error-handling code which is
+branched to, using a goto, in the event of failure.  A common source
+of errors in UNIX programs is failing to close file descriptors on
+error returns; this leaves a number of ``zombied'' file descriptors
+open, which eventually causes the process to run out of file
+descriptors and fall over.
+
+@example
+@{
+    FILE *f1=NULL, *f2=NULL, *f3=NULL;
+    int status = 0;
+
+    if ( (f1 = fopen(FILE1, "r")) == NULL) @{
+        status = errno;
+        goto error;
+    @}
+
+    /*
+     * Crunch for a while
+     */
+
+    if ( (f2 = fopen(FILE2, "w")) == NULL) @{
+        status = errno;
+        goto error;
+    @}
+
+    if ( (f3 = fopen(FILE3, "a+")) == NULL) @{
+        status = errno;
+            goto error;
+    @}
+
+    /*
+     * Do more processing.
+     */
+    fclose(f1);
+    fclose(f2);
+    fclose(f3);
+    return 0;
+
+error:
+    if (f1) fclose(f1);
+    if (f2) fclose(f2);
+    if (f3) fclose(f3);
+    return status;
+@}
+@end example
+
+@section Building and Installation
+
+The distribution of this package will probably be done as a compressed
+``tar''-format file available via anonymous FTP from SIPB.MIT.EDU.
+Retrieve @samp{pub/com_err.tar.Z} and extract the contents.  A subdirectory
+@t{profiled} should be created to hold objects compiled for profiling.
+Running ``make all'' should then be sufficient to build the library and
+error-table compiler.  The files @samp{libcom_err.a},
+@samp{libcom_err_p.a}, @samp{com_err.h}, and @samp{compile_et} should be
+installed for use; @samp{com_err.3} and @samp{compile_et.1} can also be
+installed as manual pages.
+
+Potential problems:
+
+@itemize @bullet
+
+@item Use of @code{strcasecmp}, a routine provided in BSD for
+case-insensitive string comparisons.  If an equivalent routine is
+available, you can modify @code{CFLAGS} in the makefile to define
+@code{strcasecmp} to the name of that routine.
+
+@item Compilers that defined @code{__STDC__} without providing the header
+file @code{<stdarg.h>}.  One such example is Metaware's High ``C''
+compiler, as provided at Project Athena on the IBM RT/PC workstation; if
+@code{__HIGHC__} is defined, it is assumed that @code{<stdarg.h>} is not
+available, and therefore @code{<varargs.h>} must be used.  If the symbol
+@code{VARARGS} is defined (e.g., in the makefile), @code{<varargs.h>} will
+be used.
+
+@item If your linker rejects symbols that are simultaneously defined in two
+library files, edit @samp{Makefile} to remove @samp{perror.c} from the
+library.  This file contains a version of @var{perror(3)} which calls
+@code{com_err} instead of calling @code{write} directly.
+
+@end itemize
+
+As I do not have access to non-BSD systems, there are probably
+bugs present that may interfere with building or using this package on
+other systems.  If they are reported to me, they can probably be fixed for
+the next version.

+.SH NAME
+compile_et \- error table compiler
+.SH SYNOPSIS
+.B compile_et
+file
+.SH DESCRIPTION
+.B Compile_et
+converts a table listing error-code names and associated messages into
+a C source file suitable for use with the
+.IR com_err (3)
+library.
+
+The source file name must end with a suffix of ``.et''; the file
+consists of a declaration supplying the name (up to four characters
+long) of the error-code table:
+
+.B error_table
+.I name
+
+followed by up to 256 entries of the form:
+
+.B error_code
+.I name,
+"
+.I string
+"
+
+and a final
+
+.B end
+
+to indicate the end of the table.
+
+The name of the table is used to construct the name of a subroutine
+.I initialize_XXXX_error_table
+which must be called in order for the
+.I com_err
+library to recognize the error table.
+
+The various error codes defined are assigned sequentially increasing
+numbers (starting with a large number computed as a hash function of
+the name of the table); thus for compatibility it is suggested that
+new codes be added only to the end of an existing table, and that no
+codes be removed from tables.
+
+The names defined in the table are placed into a C header file with
+preprocessor directives defining them as integer constants of up to
+32 bits in magnitude.
+
+A C source file is also generated which should be compiled and linked
+with the object files which reference these error codes; it contains
+the text of the messages and the initialization subroutine.  Both C
+files have names derived from that of the original source file, with
+the ``.et'' suffix replaced by ``.c'' and ``.h''.
+
+A ``#'' in the source file is treated as a comment character, and all
+remaining text to the end of the source line will be ignored.
+
+.SH BUGS
+
+Since
+.B compile_et
+uses a very simple parser based on
+.IR yacc (1),
+its error recovery leaves much to be desired.
