From d210ebbb09daddb2c8c8e8e77243e088b0b19c4d Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 26 Sep 2006 23:50:56 +0000 Subject: rework memory block management to be thread-safe and mostly lock-free. pa_memblock is now an opaque structure. Access to its fields is now done through various accessor functions in a thread-safe manner. pa_memblock_acquire() and pa_memblock_release() are now used to access the attached audio data. Why? To allow safe manipulation of the memory pointer maintained by the memory block. Internally _acquire() and _release() maintain a reference counter. Please do not confuse this reference counter whith the one maintained by pa_memblock_ref()/_unref()! As a side effect this patch removes all direct usages of AO_t and replaces it with pa_atomic_xxx based code. This stuff needs some serious testing love. Especially if threads are actively used. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1404 fefdeb5f-60dc-0310-8127-8f9354f1896f --- src/pulsecore/sample-util.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/pulsecore/sample-util.h') diff --git a/src/pulsecore/sample-util.h b/src/pulsecore/sample-util.h index 6b770792..04c2f6b1 100644 --- a/src/pulsecore/sample-util.h +++ b/src/pulsecore/sample-util.h @@ -36,10 +36,11 @@ typedef struct pa_mix_info { pa_memchunk chunk; pa_cvolume volume; void *userdata; + void *internal; /* Used internally by pa_mix(), should not be initialised when calling pa_mix() */ } pa_mix_info; size_t pa_mix( - const pa_mix_info channels[], + pa_mix_info channels[], unsigned nchannels, void *data, size_t length, -- cgit
