source: MondoRescue/trunk/mondo/mondo/src/libmondo-fork.c@ 795

Last change on this file since 795 was 783, checked in by Bruno Cornec, 18 years ago
  • Massive rewrite continues for memory management.
  • main structure should now have all parameters allocated dynamically
  • new lib libmr.a + dir + build process reviewed to support it.
  • new include subdir to host external definitions of the new lib
  • code now compiles. Still one remaining link issues for mondorestore. This should allow for some tests soon.

(goal is to separate completely reviewed code and functions and provide clean interfaces)
  • Property svn:keywords set to Id
