Destroy a read-write lock
#include <audio_driver.h>
ado_rwlock_destroy( pthread_rwlock_t *rwl )
- rwl
- A pointer to the pthread_rwlock_t structure for the
read-write lock.
The ado_rwlock_destroy() macro destroys the given read-write lock.
This macro is defined as
pthread_rwlock_destroy(),
or ado_rwlock_destroy_debug() if
ADO_RWLOCK_DEBUG and ADO_DEBUG
are defined.
The debug version uses
ado_debug()
to display a message to help you locate a locking problem in the driver.
For more information, see
“Debugging an audio driver”
in the Organization of a Driver chapter.
Same as
pthread_rwlock_destroy():
- EOK
- Success.
- EBUSY
- The read-write lock is still in use. The behavior of this
read-write lock is now undefined.
