source: messagelist.c @ b343c2c

release-1.8release-1.9
Last change on this file since b343c2c was d427f08, checked in by Nelson Elhage <nelhage@mit.edu>, 10 years ago
Use G_GNUC_WARN_UNUSED_RESULT Have gcc warn us when we ignore the result of a function that requires the caller to free the result, or an initilization function that can fail. This might help (slightly) with preventing leaks and segfaults. Additionally changed some functions that should never fail to not return values. (The owl_list_* functions changed only fail if list->size < 0, which we assume is not the case elsewhere.)
