This function returns the number of bytes that have been transmitted, or a value less than zero on error.

Parameters

sock	Socket to send data with
session	Addressing information for unconnected sockets, or NULL
data	The data to send.
datalen	The actual length of data.

Returns

The number of bytes written on success, or a value less than zero on error.
