From: Søren Sandmann Pedersen Date: Sat, 15 Sep 2012 17:20:52 +0000 (-0400) Subject: Move delegation of src/dest iter init into pixman-implementation.c X-Git-Tag: pixman-0.27.4~46 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ee6af72dadaf9eb049bfeb35dc9ff57c3902403a;p=platform%2Fupstream%2Fpixman.git Move delegation of src/dest iter init into pixman-implementation.c Instead of relying on each implementation to delegate when an iterator can't be initialized, change the type of iterator initializers to boolean and make pixman-implementation.c do the delegation whenever an iterator initializer returns FALSE. --- diff --git a/pixman/pixman-general.c b/pixman/pixman-general.c index 6c6bda0..42a84a0 100644 --- a/pixman/pixman-general.c +++ b/pixman/pixman-general.c @@ -37,7 +37,7 @@ #include #include "pixman-private.h" -static void +static pixman_bool_t general_src_iter_init (pixman_implementation_t *imp, pixman_iter_t *iter) { pixman_image_t *image = iter->image;
