GLib RWLockinit

void
g_rw_lock_init(
GRWLock*rw_lock
)

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.

typedefstruct{
GRWLockl;
...
}Blob;
Blob*b;
b=g_new(Blob,1);
g_rw_lock_init(&b->l);

To undo the effect of g_rw_lock_init() when a lock is no longer needed, use g_rw_lock_clear().

Calling g_rw_lock_init() on an already initialized GRWLock leads to undefined behaviour.
