source: functions.c @ 99ac28a

release-1.8release-1.9
Last change on this file since 99ac28a was 99ac28a, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Use GPid instead of pid_t for g_spawn_async's output Apparently they manage to be different on Solaris. GPid is int while pid_t is long. Better to cast the value than the pointer.
