Unlock a mutex
#include <audio_driver.h>
#define ado_mutex_unlock( mutex )
- mutex
- The mutex to unlock.
The mutex is of type pthread_mutex_t *.
The ado_mutex_unlock() macro unlocks the given mutex.
This macro is defined as
pthread_mutex_unlock(),
or ado_mutex_unlock_debug() if
ADO_MUTEX_DEBUG and ADO_DEBUG are defined.
The debug version uses
ado_debug()
to display a message
to help you locate a mutex problem in the driver.
For more information, see
“Debugging an audio driver”
in the Organization of a Driver chapter.
Same as
pthread_mutex_unlock():
- EOK
- Success.
- EINVAL
- The given mutex is invalid.
- EPERM
- The current thread doesn't own mutex.
