From 62d4fa9306fdb5dd0a1b592fd8dbdf1b679d92ca Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Thu, 30 Oct 2008 08:38:54 +0100 Subject: decoder: use bool for return values and flags Don't return 0/-1 on success/error, but true/false. Instead of int, use bool for storing flags. --- src/decoder/aac_plugin.c | 39 ++++++++++++++++++++------------------- src/decoder/audiofile_plugin.c | 11 ++++++----- src/decoder/ffmpeg_plugin.c | 12 ++++++------ src/decoder/flac_plugin.c | 29 +++++++++++++++-------------- src/decoder/mod_plugin.c | 31 ++++++++++++++++--------------- src/decoder/mp3_plugin.c | 28 ++++++++++++++-------------- src/decoder/mp4_plugin.c | 16 ++++++++-------- src/decoder/mpc_plugin.c | 18 +++++++++--------- src/decoder/oggflac_plugin.c | 2 +- src/decoder/oggvorbis_plugin.c | 24 ++++++++++++------------ src/decoder/wavpack_plugin.c | 23 ++++++++++++----------- 11 files changed, 119 insertions(+), 114 deletions(-) (limited to 'src/decoder') diff --git a/src/decoder/aac_plugin.c b/src/decoder/aac_plugin.c index 8ceed8b2b..8ae061667 100644 --- a/src/decoder/aac_plugin.c +++ b/src/decoder/aac_plugin.c @@ -34,7 +34,7 @@ typedef struct { size_t bytesConsumed;
