The following API functions of the POSIX reader-writer locks specification are implemented:
* `pthread_rwlock_init() <https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_init.html>`_
* ``pthread_rwlock_init()``
- The ``attr`` argument is not implemented and is ignored.
* ``pthread_rwlock_destroy()``
* ``pthread_rwlock_rdlock()``
* ``pthread_rwlock_wrlock()``
* ``pthread_rwlock_unlock()``
Static initializer constant ``PTHREAD_RWLOCK_INITIALIZER`` is supported.
