NAME
socket_fastopen - enable TCP Fast Open on a server-side TCP socketSYNTAX
#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);
