* added prefix to header macrosMax Kellermann2008-10-311-2/+2
| | | | | | | "LOG_H" is a macro which is also used by ffmpeg/log.h. This is ffmpeg's fault, because short macros should be reserved for applications, but since it's always a good idea to choose prefixed macro names, even for applications, we are going to do that in MPD.
* don't include os_compat.hMax Kellermann2008-10-081-1/+2
| | | | | When there are standardized headers, use these instead of the bloated os_compat.h.
* fixed ringbuf.c warningsMax Kellermann2008-08-251-1/+1
| | | | | Fix a "signed/unsigned comparison warning", and several void pointer math warnings.
* ringbuf: add thread-safe, thread-specific reset functionsEric Wong2008-06-301-0/+18
| | | | | | This will allow both the reader and writer threads to reset the ringbuffer in a thread-safe fashion. git-svn-id: https://svn.musicpd.org/mpd/trunk@7390 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* ringbuf: get_{write,read}_vector returns total bytes in both vec eltsEric Wong2008-06-301-2/+5
| | | | | This will eliminate unnecessary calls to ringbuf_{read,write}_space git-svn-id: https://svn.musicpd.org/mpd/trunk@7389 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Add a generic ring buffer implementationEric Wong2008-06-301-0/+205
This piece of code is from the JACK Audio Connection Kit (trimmed down a bit for better readability). The vector functions now reuse the common iovec struct used by writev/readv instead of reinventing an identical but differently-named struct. From the comments: > ISO/POSIX C version of Paul Davis's lock free ringbuffer C++ code. > This is safe for the case of one read thread and one write thread.
