/**\r
  Bind a name to a socket.\r
\r
  The bind routine connects a name (network address) to a socket on the local machine.\r
\r
  The\r
  <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/bind.html">POSIX</a>\r
  documentation is available online.\r
\r
  @param[in] s         Socket file descriptor returned from ::socket.\r
\r
  @param[in] name      Address of a sockaddr structure that contains the\r
                        connection point on the local machine.  An IPv4 address\r
                        of INADDR_ANY specifies that the connection is made to\r
                        all of the network stacks on the platform.  Specifying a\r
                        specific IPv4 address restricts the connection to the\r
                        network stack supporting that address.  Specifying zero\r
                        for the port causes the network layer to assign a port\r
                        number from the dynamic range.  Specifying a specific\r
                        port number causes the network layer to use that port.\r
\r
  @param[in] namelen   Specifies the length in bytes of the sockaddr structure.\r
\r
  @return     The bind routine returns zero (0) if successful and -1 upon failure.\r
              In the case of an error, ::errno contains more information.\r
