Revision 1.181 - (hide annotations) (download) (as text)
Wed Jun 30 17:07:20 2004 UTC (15 years ago) by wingman
Branch: MAIN
Changes since 1.180: +13 -11 lines
File MIME type: text/x-chdr
* Added support for single and double linked lists

* Added some more xml validation errors

* Added some TODO's

* Added MIN/MAX_<datatype> #define's. Someone should really add a check
  for limit.h if it provides these types.

* Changed default value of variant's int to MIN_INT so our config api
  can differ between non-set ints (0 is too commonly used as a real
  value). So if variant's int is MIN_INT the attribute is not written.
