socket_fastopen - enable TCP Fast Open on a server-side TCP socket
#include <libowfat/socket.h>
int socket_fastopen(int s);
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.
#include <libowfat/socket.h>
int s;
char ip[4];
uint16 p;
s = socket_tcp4b();
socket_fastopen(s);
socket_bind4_reuse(s,ip,p);
socket_listen(16);
