RWLock.init_

Initializes a #GRWLock so that it can be used.

This function is useful to initialize a lock that has been allocated on the stack, or as part of a larger structure. It is not necessary to initialise a reader-writer lock that has been statically allocated.

  typedef struct {
    GRWLock l;
    ...
  } Blob;

Blob *b;

b = g_new (Blob, 1);
g_rw_lock_init (&b->l);

To undo the effect of glib.rwlock.RWLock.init_ when a lock is no longer needed, use glib.rwlock.RWLock.clear.

Calling glib.rwlock.RWLock.init_ on an already initialized #GRWLock leads to undefined behaviour.
