+ * Function    :  write_socket_delayed
+ *
+ * Description :  Write the contents of buf (for n bytes) to
+ *                socket fd, optionally delaying the operation.
+ *
+ * Parameters  :
+ *          1  :  fd = File descriptor (aka. handle) of socket to write to.
+ *          2  :  buf = Pointer to data to be written.
+ *          3  :  len = Length of data to be written to the socket "fd".
+ *          4  :  delay = Delay in milliseconds.
+ *
+ * Returns     :  0 on success (entire buffer sent).
+ *                nonzero on error.
