Acquire an exclusive write lock on a read-write lock
#include <audio_driver.h> int ado_rwlock_wrlock( pthread_rwlock_t *rwl );
This macro acquires an exclusive write lock on the given read-write lock.
The ado_rwlock_wrlock() macro is defined as pthread_rwlock_wrlock(), or ado_rwlock_wrlock_debug(), if ADO_RWLOCK_DEBUG and ADO_DEBUG are defined. The debug version uses ado_debug() to display a message, to aid in locating a locking problem in the driver.
For more information, see “Debugging an audio driver” in the Organization of a Driver chapter.
