source: MondoRescue/trunk/mondo/mondo/common/libmondo-verify.c@ 688

Last change on this file since 688 was 688, checked in by bcornec, 18 years ago

Huge memory management patch.
Still not finished but a lot as been done.
What remains is around some functions returning strings, and some structure members.
(Could not finish due to laptop failure !)
