66 | Similar to C<down>, but does not actually decrement the counter. Instead, |
|
|
67 | when this function returns, a following call to C<down> or C<try> is |
|
|
68 | guaranteed to succeed without blocking, until the next coroutine switch |
|
|
69 | (C<cede> etc.). |
|
|

|
|
71 | Note that using C<wait> is much less efficient than using C<down>, so try |
|
|
72 | to prefer C<down> whenever possible. |
