251 | These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only |
|

252 | returns directly I<after> the tick processing (and consequently, can only wake one thread |
|

253 | per tick), while cf::wait_for_tick wakes up all waiters after tick processing. |
|
|
254 | |
|
|
255 | Note that cf::Wait_for_tick will immediately return when the server is not |
|
|
256 | ticking, making it suitable for small pauses in threads that need to run |
|
|
257 | when the server is paused. If that is not applicable (i.e. you I<really> |

263 | variable contains a L<Coro::Signal> that is broadcats after every server |
|
