socket_fastopen(3)	    Library Functions Manual	      socket_fastopen(3)

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);
