Hi I would like to know writeable fileevent while socket creation.
I'm able to understand the readable fileevent.

fileevent channelID readable ReadCB

Whenever a client places a request, the channel is ready to be read and ReadCB is called.
I could not get the usage of writeable fileevent.
Can somebody explain with a small example?
