NAME

socket_tcp - setting up TCP sockets  

SYNTAX

#include "socket_if.h"

int socket_tcp4();
int socket_tcp6();
int socket_tcp();  

DESCRIPTION

socket_tcp4 creates a non-blocking TCP/IPv4 stream socket and providing a file descriptor pointing to that socket.

socket_tcp6 creates a non-blocking TCP/IPv6 stream socket and providing a file descriptor pointing to that socket.

socket_tcp creates a non-blocking IPv6 TCP/IP socket calling socket_tcp6 unless it can't bind to IPv6 and now facilitating socket_tcp4.  

REMOTE CODES

All these routines return 0 except in case of failures, returning -1 and setting errno appropriately, without allocating any resources.  

EXAMPLE


  #include <socket_if.h>


  int t;
  char localip[16];
  char remoteip[16];
  uint16 p;


  if (ip6_isv4mapped(remoteip)) {
    t = socket_tcp4();
    socket_bind4(t,localip + 12,0);
  } else {
    t = socket_tcp6();
    socket_bind6(t,localip,0,0);
  }
  socket_connect(s,remoteip,p,0);
