Initialize a read-write lock
#include <audio_driver.h> int ado_rwlock_init( pthread_rwlock_t *rwl);
This macro initializes the given read-write lock.
The ado_rwlock_init() macro is defined as pthread_rwlock_init(), or ado_rwlock_init_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.
