606 | The sole purpose of this class is to deliver an interface to the |
|
|
607 | C<AnyEvent> module - any module using it will work inside urxvt without |
|
|
608 | further work. The only exception is that you cannot wait on condition |
|
|
609 | variables, but non-blocking condvar use is ok. What this means is that you |
|
|
610 | cannot use blocking APIs, but the non-blocking variant should work. |
