From 304449002cbc84fdcf235b5dfaec891278dd7085 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 20 Feb 2006 04:05:16 +0000 Subject: 1) Add flexible seeking support (including absolute) for memory block queues and playback streams 2) Add support to synchronize multiple playback streams 3) add two tests for 1) and 2) 4) s/PA_ERROR/PA_ERR/ 5) s/PA_ERROR_OK/PA_OK/ 6) update simple API to deal properly with new peek/drop recording API 7) add beginnings of proper validity checking on API calls in client libs (needs to be extended) 8) report playback buffer overflows/underflows to the client 9) move client side recording mcalign stuff into the memblockq 10) create typedefs for a bunch of API callback prototypes 11) simplify handling of HUP poll() events Yes, i know, it's usually better to commit a lot of small patches instead of a single big one. In this case however, this would have contradicted the other rule: never commit broken or incomplete stuff. *** This stuff needs a lot of additional testing! *** git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@511 fefdeb5f-60dc-0310-8127-8f9354f1896f --- src/tests/memblockq-test.c | 147 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 147 insertions(+) create mode 100644 src/tests/memblockq-test.c (limited to 'src/tests/memblockq-test.c') diff --git a/src/tests/memblockq-test.c b/src/tests/memblockq-test.c new file mode 100644 index 00000000..b01084da --- /dev/null +++ b/src/tests/memblockq-test.c @@ -0,0 +1,147 @@ +/* $Id$ */ + +/*** + This file is part of polypaudio. + + polypaudio is free software; you can redistribute it and/or modify + it under the terms of the GNU Lesser General Public License as published + by the Free Software Foundation; either version 2 of the License, + or (at your option) any later version. + + polypaudio is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
