# socket\_tcp6(3)

create a non-blocking IPv6 TCP/IP stream socket

## NAME

socket\_tcp6 - create a non-blocking IPv6 TCP/IP stream socket

## SYNTAX

**#include \<libowfat/socket.h\>**

int **socket\_tcp6**();

## DESCRIPTION

socket\_tcp6 creates a non-blocking IPv6 TCP/IP stream socket and returns a file descriptor pointing to that socket.  If something goes wrong, socket\_tcp6 returns -1, setting errno appropriately, without allocating any resources.

## EXAMPLE

  \#include \<libowfat/socket.h\>

  int *s*;\
   char *ip*\[16\];\
   uint16 *p*;

  *s* = socket\_tcp6();\
   socket\_bind6(s,ip,p);\
   socket\_connect6(s,ip,p,0);
