NAME

6       socket_recv4 - receive a UDP datagram
7

SYNTAX

9       #include <socket.h>
10
11       ssize_t socket_recv4(int s, char* buf, size_t len,
12                        char ip[4],uint16* port);
13

DESCRIPTION

15       socket_recv4  receives up to len bytes starting at buf from a UDP data‐
16       gram coming in on the socket s.  It writes the UDP port to port and the
17       IP address to ip, and returns the number of bytes actually received (or
18       -1 if anything went wrong).
19

RETURN VALUE

21       socket_recv4 returns the number of bytes in the  datagram  if  one  was
22       received.  If not, it returns -1 and sets errno appropriately.
23

EXAMPLE

25         #include <socket.h>
26
27         int s;
28         char ip[4];
29         uint16 p;
30         char buf[1000];
31         int len;
32
33         s = socket_tcp4();
34         socket_bind4(s,ip,p);
35         len = socket_recv4(s,buf,sizeof(buf),ip,&p);
