Acquire a shared read lock on a read-write lock
#include <audio_driver.h> ado_rwlock_rdlock( pthread_rwlock_t *rwl);
This macro acquires a shared read lock on the given read-write lock.
The ado_rwlock_rdlock macro() is defined as pthread_rwlock_rdlock(), or ado_rwlock_rdlock_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.
