Revision 1.174 - (hide annotations) (download) (as text)
Tue Jun 22 10:54:42 2004 UTC (15 years, 2 months ago) by wingman
Branch: MAIN
Changes since 1.173: +28 -17 lines
File MIME type: text/x-chdr
* Fixed -DDEBUG (wasn't supplied in lib/eggdrop and modules)

* Reformatted help and xml to match our coding rules

* Added simple memory tracking functions

* Added a debugging switch (-d, --debug) which isn't very usefull for
  anyone but me since it's a normal eggdrop run w/o the main loop ;-). It
  helps me finding mem leaks by doing

	./eggdrop -d && cat memory.log

  Yeah, will be removed, but not yet currently coz there are still ~270
  memory blocks allocated when eggdrop is shut down.
