source: MondoRescue/branches/2.2.9/mondo/src/common/libmondo-mountlist.c@ 2350

Last change on this file since 2350 was 2350, checked in by Bruno Cornec, 15 years ago

Change inerface of evaluate_mountlist and spread_flaws_across_three_lines in order to solve bugs linked to strings management in these functions. May fix a restoration crash seen by some customers
