974 | =head3 ASYNC WATCHERS - how to wake up another event loop |
|
|
975 | |
|
|
976 | Async watchers are provided by EV, but have little use in perl directly, as perl |
|
|
977 | neither supports threads nor direct access to signal handlers or other |
|
|
978 | contexts where they could be of value. |
|
|
979 | |
|
|
980 | It is, however, possible to use them from the XS level. |
