From de5f852f38d644edf995a810c34b4d24dbfbd740 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 27 Jun 2017 18:32:49 +0100 Subject: main_loop: Make main_loop_wait() return void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The last users of main_loop_wait() that cared about the return value have now been changed to no longer use it. Drop the now-useless return value and make the function return void. We avoid the awkwardness of ifdeffery to handle the 'ret' variable in main_loop_wait() only being wanted if CONFIG_SLIRP by simply dropping all the ifdefs. There are stub implementations of slirp_pollfds_poll() and slirp_pollfds_fill() already in stubs/slirp.c which do nothing, as required.
