[pacman-dev] [PATCH 2/2] Add ALPM_ERR_OK = 0 to _alpm_err_t

ivy.foster at gmail.com ivy.foster at gmail.com
Sat Sep 3 02:08:17 UTC 2016


From: Ivy Foster <ivy.foster at gmail.com>

Functions that expect an _alpm_err_t can now get a true one, even on
success. Since previous practice was to return 0 (not included in the
_alpm_err_t enum type), anything that just checks !err or (err == 0)
should work as is.
