GLibStaticRWLockreader_lock

Locks lock for reading. There may be unlimited concurrent locks for reading of a GStaticRWLock at the same time. If lock is already locked for writing by another thread or if another thread is already waiting to lock lock for writing, this function will block until lock is unlocked by the other writing thread and no other writing threads want to lock lock. This lock has to be unlocked by g_static_rw_lock_reader_unlock().

GStaticRWLock is not recursive. It might seem to be possible to recursively lock for reading, but that can result in a deadlock, due to writer preference.

This method is not directly available to language bindings.
