+
+&h2(DESCRIPTION)
+The &cw(rmr_set_low_latency) function enables &ital(TCP NO_DELAY) if
+the underlying transport library supports it.
+This might be useful for applications which must send messages at a maximum
+rate.
+
+&space
+A call to this function will cause all subsequent connections made by the application
+to set the no delay (low latency) option.
+When no delay is needed, it is recommended that this function be called immediately upon a successful call to
+the RMR initialisation function.
+
+&space
+The effect of setting "low latency" mode is to disable Nagel's algorithm and to send a packet
+on a connection as soon as it is given to the TCP transport.
+When this option is not enabled, TCP may employ Nagel's algorithm and hold the packet
+with the assumption that it can be combined with another and sent in the same datagram
+in an effort to improve bandwidth but at the expense of added latency.
+
+&h2(RETURN VALUE)
+There is no return value.
+
+
+&h2(ERRORS)
+This function does not generate any errors.
