2020-08-25pcm_plugin: Update pcm state in sync_ptr opsRohit kumar
PCM state is currently not updated in plugin. Add support to update the state variable.
2020-08-25include: tinyalsa: Add PCM state macrosRohit kumar
Add PCM_STATE_OPEN and PCM_STATE_SETUP macros so that it can be utilized by plugin to update sync_ptr state.

2020-06-05cmake: specify c99Ethan Sommer
Set standard to c99, require it, disable language extensions. Define _POSIX_C_SOURCE to 200809L so time.h declares struct timespec. Add -Wpedantic to find use of language extensions. snd_card_plugin.c: remove one unnecessary ';' to make -Wpedantic work
2020-06-05include/tinyalsa/plugin.h: include time.hEthan Sommer
Older versions of linux's API header sound/asound.h accidentally rely on indirect declaration of struct timespec, which isn't reliable, so include time.h before it to support older versions of sound/asound.h properly

Various cmake improvements
2020-06-04Various cmake improvementsEthan Sommer
Use scripts/version.sh, and set version in project() using its output. Instead of using a variable to store the definition of TINYALSA_USES_PLUGINS, and adding it as a compile option, use a generator expression to define it in target_compile_definitions when the option is enabled. Set BUILD_SHARED_LIBS to on by default. Add options to disable examples and utils. Instead of using SRCS and HDRS variables, set PUBLIC_HEADER property on tinyalsa to install the headers along with the target. Set library version, so the shared library will have version suffixes. Check that C warning flags are supported instead of adding them unconditionally. Use ${CMAKE_DL_LIBS} instead of hardcoding "dl", and add it to tinyalsa's link interface and link depends, instead of linking it in the examples and utils. Add the "include" directory as a PUBLIC include directory to tinyalsa, instead of making it PRIVATE and adding it to examples and utils as well, because anything linking the tinyalsa target will need to include "include". Instead of using macros for building examples and utils, use a for loop. Include cmake's GNUInstallDirs to automatically correctly populate installation dir variables, instead of doing it manually.

2020-06-02mixer: Fix memory leak and other issues in mixer eventRohit kumar
Fix memory leak in mixer_wait_event(). Also, poll should be unblocked after increasing event_cnt in mixer_plugin, otherwise event_cnt can become negative during read_event. Fix the same.
2020-06-02mixer: Add plugin support for mixer_consume/read_eventRohit kumar
snd_ctl_event is needed by client to get details of event received. Introduce mixer_read_event() with plugin support to support this.

MAP_FILE is a non-standard mmap flag, and has no effect on conformant systems.

Change shebang to #!/bin/sh. Remove usage of non-POSIX 'local' builtin, and replace it with using a function's positional parameters to store variables, as they are local to the function.

tinyalsa: use strncpy instead of memcpy to copy string constant
2020-04-24tinyalsa: mixer_plugin: remove dummy strings for sound cardMinecrell
There does not really seem to be an usage for these dummy string, so let's remove them.
2020-04-23tinyalsa: use strncpy instead of memcpy to copy string constantMinecrell
memcpy() is arguably wrong when copying these string constants. The string constants will usually just be as long as necessary, so we might copy some random memory behind it and eventually crash. Use strncpy() instead to avoid copying characters after the null terminator. For some reason the strings in snd_ctl_card_info use unsigned chars, so we need a cast to char* to make it compile unfortunately... This fixes the following compile error on ppc64le: In function 'mixer_plug_get_card_info', inlined from 'mixer_plug_ioctl' at mixer_plugin.c:371:15: mixer_plugin.c:333:5: error: 'memcpy' forming offset [9, 16] is out of the bounds [0, 8] [-Werror=array-bounds] 333 | memcpy(card_info->id, "card_id", sizeof(card_info->id)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Not sure why that warning does not exist on other architectures.
