NAME
       socket_recv4 - receive a UDP datagram

SYNTAX
       #include <socket.h>

       ssize_t socket_recv4(int s, char* buf, size_t len,
			char ip[4],uint16* port);

DESCRIPTION
       socket_recv4  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).

RETURN VALUE
       socket_recv4 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[4];
	 uint16 p;
	 char buf[1000];
	 int len;

	 s = socket_tcp4();
	 socket_bind4(s,ip,p);
	 len = socket_recv4(s,buf,sizeof(buf),ip,&p);
