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);
