=head1 NAME
ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load
arbitrary error strings
=head1 SYNOPSIS
#include <openssl/err.h>
void ERR_load_strings(int lib, ERR_STRING_DATA str[]);
int ERR_get_next_error_library(void);
unsigned long ERR_PACK(int lib, int func, int reason);
=head1 DESCRIPTION
ERR_load_strings() registers error strings for library number B<lib>.
B<str> is an array of error string data:
typedef struct ERR_string_data_st
{
unsigned long error;
char *string;
} ERR_STRING_DATA;
The error code is generated from the library number and a function and
reason code: B<error> = ERR_PACK(B<lib>, B<func>, B<reason>).
ERR_PACK() is a macro.
The last entry in the array is {0,0}.
ERR_get_next_error_library() can be used to assign library numbers
to user libraries at runtime.
=head1 RETURN VALUE
ERR_load_strings() returns no value. ERR_PACK() return the error code.
ERR_get_next_error_library() returns a new library number.
=head1 SEE ALSO
L<err(3)|err(3)>, L<ERR_load_strings(3)|ERR_load_strings(3)>
=head1 HISTORY
ERR_load_error_strings() and ERR_PACK() are available in all versions
of SSLeay and OpenSSL. ERR_get_next_error_library() was added in
SSLeay 0.9.0.
