184=item my $guard = cf::guard { BLOCK }
185
186Run the given callback when the guard object gets destroyed (useful for
187coroutine cancellations).
188
189You can call C<< ->cancel >> on the guard object to stop the block from
190being executed.

207
208Wait until the given lock is available. See cf::lock_acquire.
209
210=item my $lock = cf::lock_acquire $string
211
212Wait until the given lock is available and then acquires it and returns
213a guard object. If the guard object gets destroyed (goes out of scope,
214for example when the coroutine gets canceled), the lock is automatically
215returned.
216
217Lock names should begin with a unique identifier (for example, cf::map::find
218uses map_find and cf::map::load uses map_load).

1487
1488Freezes the player and moves him/her to a special map (C<{link}>).
1489
1490The player should be reaosnably safe there for short amounts of time. You
1491I<MUST> call C<leave_link> as soon as possible, though.
1492
1493=item $player_object->leave_link ($map, $x, $y)
1494
1495Moves the player out of the specila link map onto the given map. If the
1496map is not valid (or omitted), the player will be moved back to the
1497location he/she was before the call to C<enter_link>, or, if that fails,
1498to the emergency map position.
1499
1500Might block.
