From: Andre Noll Date: Sun, 5 Apr 2015 02:30:10 +0000 (+0000) Subject: Do not check the return value of para_printf(). X-Git-Tag: v0.5.6~94^2~31 X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=2edd5e54e7443ed42d4c4e56c2efb242956f818b Do not check the return value of para_printf(). This function rarely fails, and if it does, we don't care too much. On the other hand, checking the return value of each call to para_printf() clutters the code considerably, especially in the error paths where there is already an error code we have to keep. This commit simply removes all error checking for para_printf(), resulting in code which is easier to follow and less error-prone. --- diff --git a/afs.c b/afs.c index 53fa5379..eb848089 100644 --- a/afs.c +++ b/afs.c @@ -575,11 +575,11 @@ static void com_select_callback(int fd, const struct osl_object *query) .max_size_handler = afs_max_size_handler, };
