|
|
* Revision 1.9 2001/10/23 21:21:03 jongfoster
|
|||
|
|
* New error handling - error codes are now jb_errs, not ints.
|
|||
|
|
* Changed the way map() handles out-of-memory, to dramatically
|
|||
|
|
* reduce the amount of error-checking clutter needed.
|
|||
|
|
*
|
|||
|
|
* Revision 1.8 2001/09/16 17:30:24 jongfoster
|
|||
|
|
* Fixing a compiler warning.
|
|||
|
|
*
|
|||
|
|
* Revision 1.7 2001/09/16 13:20:29 jongfoster
|
|||
|
|
* Rewrite of list library. Now has seperate header and list_entry
|
|||
|
|
* structures. Also added a large sprinking of assert()s to the list
|
|||
|
|
* code.
|
|||
|
|
*
|
|||
|
|
* Revision 1.6 2001/08/05 16:06:20 jongfoster
|
|||
|
|
* Modifiying "struct map" so that there are now separate header and
|
|||
|
|
* "map_entry" structures. This means that functions which modify a
|
|||
|
|
* map no longer need to return a pointer to the modified map.
|
|||
|
|
* Also, it no longer reverses the order of the entries (which may be
|
|||
|
|
* important with some advanced template substitutions).
|
|||
|
|
*
|
|||
|
|
* Revision 1.5 2001/07/29 18:43:08 jongfoster
|
|||
|
|
* Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
|
|||
|
|
* ANSI C rules.
|
|||
|
|
*
|
|||
|
|
* Revision 1.4 2001/06/29 13:30:37 oes
|
|||
|
|
* - Introduced enlist_unique_header()
|
|||
|
|
* - Removed logentry from cancelled commit
|
|||
|
|
*
|
|||
|
|
* Revision 1.3 2001/06/03 11:03:48 oes
|
|||
|
|
* introduced functions for new list type "map": map(), lookup(),
|
|||
|
|
* free_map(), and extended enlist_unique
|
|||
|
|
*
|
|||
|
|
* Revision 1.2 2001/06/01 18:49:17 jongfoster
|
|||
|
|
* Replaced "list_share" with "list" - the tiny memory gain was not
|
|||
|
|
* worth the extra complexity.
|
|||
|
|
*
|
|||
|
|
* Revision 1.1 2001/05/31 21:11:53 jongfoster
|
|||
|
|
* - Moved linked list support to new "list.c" file.
|
|||
|
|
* Structure definitions are still in project.h,
|
|||
|
|
* function prototypes are now in "list.h".
|
|||
|
|
* - Added support for "struct list_share", which is identical
|
|||
|
|
* to "struct list" except it saves memory by not duplicating
|
|||
|
|
* the strings. Obviously, this only works if there is some
|
|||
|
|
* other way of managing the memory used by the strings.
|
|||
|
|
* (These list_share lists are used for lists which last
|
|||
|
|
* for only 1 request, and where all the list entries are
|
|||
|
|
* just coming directly from entries in the actionsfile.)
|
|||
|
|
* Note that you still need to destroy list_share lists
|
|||
|
|
* properly to free the nodes - it's only the strings
|
|||
|
|
* which are shared.
|
|||
