send_token()

This function sends a token or message.

Example A–18 send_token()

/*
 * Function: send_token
 *
 * Purpose: Writes a token to a file descriptor.
 *
 * Arguments:
 *
 *      s               (r) an open file descriptor
 *      tok             (r) the token to write
 *
 * Returns: 0 on success, -1 on failure
 *
 * Effects:
 *
 * send_token writes the token length (as a network long) and then the
 * token data to the file descriptor s.  It returns 0 on success, and
 * -1 if an error occurs or if it could not write all the data.
