source: global.c @ 60b49a7

release-1.8release-1.9
Last change on this file since 60b49a7 was 47e0a6a, checked in by David Benjamin <davidben@mit.edu>, 11 years ago
Punt a number of g_new NULL checks, various minor cleanups No real need to check g_new's return value as it always succeeds. (Or destroys the universe^Wprocess in embarrassment.) Also make owl_global manage the lifetime of the kill buffer since it's part of owl_global now. And replace a g_new/strncpy with a g_strndup. It's shorter.
