source: MondoRescue/branches/stable/mondo/mondo/common/newt-specific.c@ 820

Last change on this file since 820 was 797, checked in by andree, 18 years ago

newt-specific.c:
Fixed compile error by removing superfluous quotes in
kill_anything_like_this().

libmondo-fork.c:
Fixed compiler warning on 64bit platforms regarding the output of the
result of ftello() by casting it to long long (and it's actually
signed).

libmondo-fifo.c:
Added %s for ps_options in kill_buffer(). Also fixes compiler warning.

58 compare_mode(), so that tape users may benefit too
59
6004/24
61- added lots of assert()'s and log_OS_error()'s
62- cleaned up a few uninitialized strings (valgrind)
