socket_udp43diet

Usage

Overview

socket_udp4 creates a non-blocking UDP/IP datagram socket and returns a file descriptor pointing to that socket. If something goes wrong, socket_udp4 returns -1, setting errno appropriately, without allocating any resources.

Examples

#include <socket.h>

int s;
char ip[4];
uint16 p;

s = socket_udp4();
socket_bind4(s,ip,p);
socket_connect4(s,ip,p);
