178This array contains the results of the last C<invoke ()> call. When

270Wait until the given lock is available. See cf::lock_acquire.
271

273
274Wait until the given lock is available and then acquires it and returns
275a Coro::guard object. If the guard object gets destroyed (goes out of scope,
276for example when the coroutine gets canceled), the lock is automatically
277returned.
278
279Locks are *not* recursive, locking from the same coro twice results in a
280deadlocked coro.
281
282Lock names should begin with a unique identifier (for example, cf::map::find
283uses map_find and cf::map::load uses map_load).
