link error for gai_strerror and inet_ntop

[illusionist]

Hi,
the code aim is too display ip address of name passed in command line but the code is unable to link up
I am using dev-c++ and i have added library wsock32 and ws_s32
still it give link error for gai_strerror and inet_ntop
here is the code:

01    /*
02	** showip.c -- show IP addresses for a host given on the command line
03	*/
04	#include <stdio.h>
05	#include <string.h>
06	#include <windows.h>
07	#include <winsock2.h>
08	#include <ws2tcpip.h>
09	  
10	 
11	 
12	 
13	int main(int argc, char *argv[])
14	{struct addrinfo hints, *res, *p;
15	int status;
16	char ipstr[INET6_ADDRSTRLEN];
17	WSADATA wsaData; // if this doesn't work
18	//WSAData wsaData; // then try this instead
19	// MAKEWORD(1,1) for Winsock 1.1, MAKEWORD(2,0) for Winsock 2.0:
20	if (WSAStartup(MAKEWORD(2,0), &wsaData) != 0) {
21	fprintf(stderr, "WSAStartup failed.\n");
22	exit(1);
23	}
24	if (argc != 2) {
25	fprintf(stderr,"usage: showip hostname\n");
26	return 1;
27	}
28	memset(&hints, 0, sizeof hints);
29	hints.ai_family = AF_UNSPEC; // AF_INET or AF_INET6 to force version
30	hints.ai_socktype = SOCK_STREAM;
31	if ((status = getaddrinfo(argv[1], NULL, &hints, &res)) != 0) {
32	fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(status));
33	return 2;
34	}
35	printf("IP addresses for %s:\n\n", argv[1]);
36	for(p = res;p != NULL; p = p->ai_next) {
37	void *addr;
38	char *ipver;
39	// get the pointer to the address itself,
40	// different fields in IPv4 and IPv6:
41	if (p->ai_family == AF_INET) { // IPv4
42	struct sockaddr_in *ipv4 = (struct sockaddr_in *)p->ai_addr;
43	addr = &(ipv4->sin_addr);
44	ipver = "IPv4";
45	} else { // IPv6
46	struct sockaddr_in6 *ipv6 = (struct sockaddr_in6 *)p->ai_addr;
47	addr = &(ipv6->sin6_addr);
48	ipver = "IPv6";
49	}
50	// convert the IP to a string and print it:
51	inet_ntop(p->ai_family, addr, ipstr, sizeof ipstr);
52	printf(" %s: %s\n", ipver, ipstr);
53	}
54	freeaddrinfo(res); // free the linked list
55	WSACleanup();
56	return 0;
57	}

Any idea what i am missing???

Indentation. You are missing a whole helluva lot of indentation.

Other than crappy coding, it works for me. (Gentoo Linux, 2.6.31 - with modifications to remove the WinSock stuff, of course)

ipver should be a const char *, and you need indentation. What fails on your system? (What symptom do you see that makes you think it doesn't work?)

Straight from your first thread:

Have you tried library MSDN tells to use?

And frigging indent your code. Nobody can read that.
