socket_fastopen — enable TCP Fast Open on a server-side TCP socket

Syntax

#include <socket.h>

int socket_fastopen(int s);

Description

socket_fastopen enables TCP Fast Open support on a server-side TCP socket. Call this before socket_listen(). If the platform does not support this functionality, returns -1 and sets errno to ENOPROTOOPT (or ENOSYS if the platform does not define ENOPROTOOPT).

Normally socket_fastopen returns 0. If anything goes wrong, socket_fastopen returns -1, setting errno appropriately.

Example

#include <socket.h>

int s;
char ip[4];
uint16 p;

s = socket_tcp4b();
socket_fastopen(s);
socket_bind4_reuse(s,ip,p);
socket_listen(16);
