`socket_nodelay`

#include "sflsock.h"
int
socket_nodelay (
    sock_t handle)

Synopsis

Disables Nagle's algorithm for the specified socket; use this when you want to ensure that data is sent outwards as fast as possible, and when you are certain that Nagle's algorithm is causing a slowdown in performance. Recommended for HTTP, but not recommended for telnet. Returns 0 if okay, SOCKET_ERROR if there was a problem.
