From 5a898c15e79ab87d2466e61549fcc20ce115c67e Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Mon, 23 Feb 2009 09:29:56 +0100 Subject: output_api: play() returns a length The old API required an output plugin to not return until all data passed to the play() method is consumed. Some output plugins have to loop to fulfill that requirement, and may block during that. Simplify these, by letting them consume only part of the buffer: make play() return the length of the consumed data. --- src/output_plugin.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/output_plugin.h') diff --git a/src/output_plugin.h b/src/output_plugin.h index b652dc44..8a2bcada 100644 --- a/src/output_plugin.h +++ b/src/output_plugin.h @@ -92,8 +92,10 @@ struct audio_output_plugin { /** * Play a chunk of audio data. + * + * @return the number of bytes played, or 0 on error */ - bool (*play)(void *data, const char *playChunk, size_t size); + size_t (*play)(void *data, const char *chunk, size_t size); /** * Try to cancel data which may still be in the device's @@ -167,7 +169,7 @@ ao_plugin_send_tag(const struct audio_output_plugin *plugin, plugin->send_tag(data, tag); } -static inline bool +static inline size_t ao_plugin_play(const struct audio_output_plugin *plugin, void *data, const void *chunk, size_t size) { -- cgit v1.2.3
