⚠️ Deprecated ⚠️

This is deprecated since version 2.32.

Use g_rw_lock_writer_unlock() instead

Unlocks @lock. If a thread is waiting to lock @lock for writing and all locks for reading have been unlocked, the waiting thread is woken up and can lock @lock for writing. If no thread is waiting to lock @lock for writing, and some thread or threads are waiting to lock @lock for reading, the waiting threads are woken up and can lock @lock for reading.
