cl:base-string or an 8-bit
A function designator for a function of 1 argument.
A lower bounding index designator for buffer.
An upper bounding index designator for buffer.
nil or a non-negative real.
A function designator.
A Lisp object.
async-io-state-send-message asynchronously sends a message from buffer between start and end. The socket in async-io-state must be connected. When the send is successful, callback is called with async-io-state as its only argument.
error-callback, timeout, start, end and user-info have the same meaning as in async-io-state-write-buffer.
async-io-state-send-message is typically used only with an async-io-state containing a UDP socket, created by create-async-io-state-and-udp-socket, create-async-io-state-and-connected-udp-socket or calling create-async-io-state with udp non-nil.
For unconnected UDP sockets, use async-io-state-send-message-to-address.
