19 Send data using a network connection.
21 The ::send routine queues data to the network for transmission.

24 documentation is available online.
26 @param [in] s Socket file descriptor returned from ::socket.
28 @param [in] buffer Address of a buffer containing the data to send.
30 @param [in] length Length of the buffer in bytes.
32 @param [in] flags Message control flags
34 @returns ::send returns the number of data bytes that were
35 sent and -1 when an error occurs. In the case of
36 an error, errno contains more details.
