source: owl.h @ 892e897

release-1.4release-1.5release-1.6release-1.7release-1.8release-1.9
Last change on this file since 892e897 was 24ccc01, checked in by Nelson Elhage <nelhage@mit.edu>, 12 years ago
Replace owl_message_create_from_zwriteline with owl_message_create_from_zwrite. By passing in a zwrite structure instead of a line, we make it easier to construct faked messages without having to go through generaring and parsing a zwrite command line. We change owl_zephyr_handle_ack to fake a zwrite structure, fixing the segfault on zephyring users with quotes (fixes #94), as well as logging errors sending instanced personals slightly better.
