socket_recv6(3) 					     Library Functions Manual						   socket_recv6(3)

NAME

       socket_recv6 - receive a UDP datagram

SYNTAX

       #include <socket.h>

       ssize_t socket_recv6(int s, char* buf, size_t len,
	       char ip[16], uint16* port, uint32* scope_id);

DESCRIPTION

       socket_recv6  receives  up  to len bytes starting at buf from a UDP datagram coming in on the socket s.	It writes the UDP port to port and
       the IP address to ip, and returns the number of bytes actually received (or -1 if anything went wrong).

       For link-local addresses, scope_id will become the network interface number, which can  be  translated  into  the  name	of  the  interface
       ("eth0") with socket_getifname.

RETURN VALUE

       socket_recv6 returns the number of bytes in the datagram if one was received.  If not, it returns -1 and sets errno appropriately.

EXAMPLE

	 #include <socket.h>

	 int s;
	 char ip[16];
	 uint16 p;
	 char buf[1000];
	 int len;
	 uint32 scope_id;

	 s = socket_tcp4();
	 socket_bind6(s,ip,p);
	 len = socket_recv6(s,buf,sizeof(buf),ip,&p,&scope_id);

socket_sendto - Sends a message to a socket, whether it is connected or not

SYNOPSIS

       int socket_sendto (resource  $socket, string  $buf, int	$len, int  $flags, string  $addr, [int	$port])

DESCRIPTION

	The function socket_sendto(3) sends $len bytes from $buf through the socket $socket to the $port at the address $addr.

PARAMETERS

	      o $socket
		- A valid socket resource created using socket_create(3).

	      o $buf
		- The sent data will be taken from buffer $buf.

	      o $len
		-$len bytes from $buf will be sent.

	      o $flags
		- The value of $flags can be any combination of the following flags, joined with the binary OR ( |) operator.

	      Possible values for $flags

	      | 	     | an appropriate notification of this at the end of |
	      | 	     | the sent data. The sent data completes the trans- |

	      +--------------+---------------------------------------------------+
	      o $addr
		- IP address of the remote host.

	      o $port
		-$port is the remote port number at which the data will be sent.

RETURN VALUES

       socket_sendto(3) returns the number of bytes sent to the remote host, or FALSE if an error occurred.
