pthread_rwlock_unlock - release a read/write lock
#include <pthread.h> int pthread_rwlock_unlock(pthread_rwlock_t *lock);
The pthread_rwlock_unlock() function is used to release the read/write lock previously obtained by pthread_rwlock_rdlock(), pthread_rwlock_wrlock(), pthread_rwlock_tryrdlock(), or pthread_rwlock_trywrlock().
If successful, the pthread_rwlock_unlock() function will return zero. Otherwise an error number will be returned to indicate the error. The results are undefined if lock is not held by the calling thread.
The pthread_rwlock_unlock() function may fail if: [EINVAL] The value specified by lock is invalid. [EPERM] The current thread does not own the read/write lock.
The pthread_rwlock_unlock() function is expected to conform to Version 2 of the Single UNIX Specification.
The pthread_rwlock_unlock() function first appeared in FreeBSD 3.0 and OpenBSD 2.5. MirOS BSD #10-current August 4, 1998 1
