thanks for your response. Why a timer is required ?, my expectation is that
my function be called when the client socket is ready for write again. My
function is encoding video packets so i expect this:
1. initial handler called, setup the write event callback
2. once the client socket is ready for write, invoke my write_event
3. write the packet
4. repeat #2 and #3 until the callback decide to finish the request
is that possible ?
