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

SYNTAX
       #include	<libowfat/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 <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);
