source: MondoRescue/branches/2.2.10/mondo/src/common/libmondo-fork.c@ 2421

Last change on this file since 2421 was 2421, checked in by Bruno Cornec, 15 years ago
  • Remove some compiler warnings on main
  • Adds function mr_chomp and mr_strip_char and use them in mr_date and call_program_and_get_last_line_of_output
  • Fix call_program_and_get_last_line_of_output to return the right result using a temp file instead of popen
  • Fix an issue in mr_getline_int in case of eof (returns now an empty string)
  • Sequencing of Init of bkpinfo reviewed
  • Property svn:keywords set to Id
