source: MondoRescue/branches/2.2.5/mondo/src/mondoarchive/mondo-cli.c@ 1645

Last change on this file since 1645 was 1645, checked in by Bruno Cornec, 17 years ago

Render bkpinfo global (potential issue on thread, but should not be a problem as that structure is indeed static during archive)
Should solve the tmpdir issue from previous rev.
May still not compile
