Unlock the attribute structure
#include <audio_driver.h>
int32_t ado_mixer_unlock( ado_mixer_t *mixer );
- mixer
- A pointer to the ado_mixer_t structure for the mixer.
The ado_mixer_unlock() function
unlocks the attribute structure.
This function is a cover of
iofunc_attr_unlock()
using the mixer attributes.
The library automatically locks the mixer's attributes structure
before any low-level mixer code is called, so you need this function only if
some other functions, such as the PCM functions, need to manipulate the
mixer structure.
- EOK
- Success.
- EAGAIN
- On the first use, all kernel mutex objects were in use.
