NAME

socket_recv4 - receive a UDP datagram

SYNTAX

#include <libowfat/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 <libowfat/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);
