|
The libevent API provides a mechanism to execute a callback function
|
|
when a specific event occurs on a file descriptor or after a timeout
|
|
has been reached. Furthermore, libevent also support callbacks due
|
|
to signals or regular timeouts.
|
|
|
|
libevent is meant to replace the event loop found in event driven
|
|
network servers. An application just needs to call event_dispatch()
|
|
and then add or remove events dynamically without having to change
|
|
the event loop.
