+.. c:function:: PyThreadState PyGILState_GetThisThreadState()
+ Get the current thread state for this thread. May return ``NULL`` if no
+ GILState API has been used on the current thread. Note that the main thread
+ always has such a thread-state, even if no auto-thread-state call has been
+ made on the main thread. This is mainly a helper/diagnostic function.
