Description

The GRecMutex struct is an opaque data structure to represent a recursive mutex. It is similar to a #GMutex with the difference that it is possible to lock a GRecMutex multiple times in the same thread without deadlock. When doing so, care has to be taken to unlock the recursive mutex as often as it has been locked.

If a #GRecMutex is allocated in static storage then it can be used without initialisation. Otherwise, you should call g_rec_mutex_init() on it and g_rec_mutex_clear() when done.

A GRecMutex should only be accessed with the g_rec_mutex_ functions.
