Sets our main struct and passes it to the parent class.
Frees the resources allocated to a recursive mutex with g_rec_mutex_init().

Initializes a #GRecMutex so that it can be used.
Locks @rec_mutex. If @rec_mutex is already locked by another thread, the current thread will block until @rec_mutex is unlocked by the other thread. If @rec_mutex is already locked by the current thread, the 'lock count' of @rec_mutex is increased. The mutex will only become available again when it is unlocked as many times as it has been locked.
Tries to lock @rec_mutex. If @rec_mutex is already locked by another thread, it immediately returns %FALSE. Otherwise it locks @rec_mutex and returns %TRUE.
Unlocks @rec_mutex. If another thread is blocked in a g_rec_mutex_lock() call for @rec_mutex, it will become unblocked and can lock @rec_mutex itself.
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.
