RMR LIBRARY FUNCTIONS
NAME
rmr_set_low_latency
SYNOPSIS
#include <rmr/rmr.h>
void rmr_set_low_latency( void* vctx );
DESCRIPTION
The rmr_set_low_latency
function enables TCP NO_DELAY
if the underlying transport library supports it. This might
be useful for applications which must send messages at a
maximum rate.
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.
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.
RETURN VALUE
There is no return value.
ERRORS
This function does not generate any errors.
