From 4ffda3f05b034b55eb5159e0268a34c14b46e686 Mon Sep 17 00:00:00 2001 From: Rémy Oudompheng Date: Sun, 10 Apr 2011 00:04:54 +0200 Subject: libalpm: consistently use int as return type for option setters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently the only error case then when handle == NULL. However several handle functions return -1 on this error, and a uniform API makes things simpler.
