/**
  Send data using a network connection.

  The send routine queues data to the network for transmission.
  This routine is typically used for SOCK_STREAM sockets where the target
  system was specified in the ::connect call.

  The
  <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/send.html">POSIX</a>
  documentation is available online.

  @param [in] s         Socket file descriptor returned from ::socket.

  @param [in] buffer    Address of a buffer containing the data to send.

  @param [in] length    Length of the buffer in bytes.

  @param [in] flags     Message control flags

  @return     This routine returns the number of data bytes that were
              sent and -1 when an error occurs.  In the case of
              an error, ::errno contains more details.
