Helping The others Realize The Advantages Of sme
typical watcher callback, you simply commence the idle watcher. The true processing is completed while in the idle watcher callback. This will cause libev to continually poll and
It usually aliases towards the "double" type in C. When you need to do any calculations on it, you need to deal with it as some floating level price. Not like the name component "stamp" may reveal, It is additionally employed for time dissimilarities (e.g. delays) throughout libev. Error Handling

There is no guidance for kqueue, as evidently it cannot be accustomed to implement this features, because of the prerequisite of having a file descriptor open on

Libev comes with some simplistic wrapper classes for C ++ that predominantly let you use some ease methods to get started/halt watchers and
Method four: Tend not to use a prepare or Test watcher since the module you need to embed isn't flexible more than enough to guidance it. Alternatively, you are able to override their
