From d5187ce694cca1c5bd05bd562d9494e7387a86d0 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sun, 7 Sep 2008 19:14:39 +0200 Subject: fix -Wcast-qual -Wwrite-strings warnings The previous patch enabled these warnings. In Eric's branch, they were worked around with a generic deconst_ptr() function. There are several places where we can add "const" to pointers, and in others, libraries want non-const strings. In the latter, convert string literals to "static char[]" variables - this takes the same space, and seems safer than deconsting a string literal. --- src/audioOutputs/audioOutput_jack.c | 17 +++++++++-------- src/audioOutputs/audioOutput_shout.c | 4 ++-- src/inputPlugins/mod_plugin.c | 17 +++++++++++++---- src/inputPlugins/wavpack_plugin.c | 12 ++++++++---- src/pcm_utils.c | 19 ++++++++++--------- 5 files changed, 42 insertions(+), 27 deletions(-) (limited to 'src') diff --git a/src/audioOutputs/audioOutput_jack.c b/src/audioOutputs/audioOutput_jack.c index 8818bb739..77ee077a4 100644 --- a/src/audioOutputs/audioOutput_jack.c +++ b/src/audioOutputs/audioOutput_jack.c @@ -31,8 +31,8 @@ static const size_t sample_size = sizeof(jack_default_audio_sample_t);
