Revision history:
|
|
|
|
|
|
1.00 2001, Feb 19 Patrick Pollet <patrick.pollet@insa-lyon.fr>
|
|
Was named nwdslisttrees.c
|
|
|
|
1.01 2001, March 10 Patrick Pollet <patrick.pollet@insa-lyon.fr>
|
|
Renamed from nwdslisttrees.c to ncplisttrees.c
|
|
This program is meant to be called by a TCL/tk from end in -Q mode
|
|
so it should emit the word "failed" in case of trouble
|
|
somewhere in the line.
|
|
#removed useless -U and -P parameters
|
|
#rewritten for use of corrected NWDSReturnBlockOfTrees
|
|
#232: Added test code for the 64 mallocs
|
|
|
|
1.02 2001, March 12 Patrick Pollet <patrick.pollet@insa-lyon.fr>
|
|
Added -A option to list only trees where current user is authenticated.
|
|
for use from TCL/tk GUIS
|
|
