daytimetcpcli.c [Problem]

Hello,
I have a problem with err_***..

The code is :

Code:

#include	"unp.h"


int main(int argc, char **argv)
{
	int					sockfd, n;
	char				recvline[MAXLINE + 1];
	struct sockaddr_in	servaddr;

	if (argc != 2)
		err_quit("usage: a.out <IPaddress>");

	if ( (sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0)
		err_sys("socket error");

	bzero(&servaddr, sizeof(servaddr));
	servaddr.sin_family = AF_INET;
	servaddr.sin_port   = htons(13);	/* daytime server */
	if (inet_pton(AF_INET, argv[1], &servaddr.sin_addr) <= 0)
		err_quit("inet_pton error for %s", argv[1]);

	if (connect(sockfd, (SA *) &servaddr, sizeof(servaddr)) < 0)
		err_sys("connect error");

	while ( (n = read(sockfd, recvline, MAXLINE)) > 0) {
		recvline[n] = 0;	/* null terminate */
		if (fputs(recvline, stdout) == EOF)
			err_sys("fputs error");
	}
	if (n < 0)
		err_sys("read error");

	exit(0);
}

and the unp.h is : http://wklej.org/id/53340/

and the problems are :

daytimetcpcli.c.text+0x35): undefined reference to `err_quit'
daytimetcpcli.c.text+0x6c): undefined reference to `err_sys'
daytimetcpcli.c.text+0xd9): undefined reference to `err_quit'
daytimetcpcli.c.text+0x106): undefined reference to `err_sys'
daytimetcpcli.c.text+0x13e): undefined reference to `err_sys'
daytimetcpcli.c.text+0x182): undefined reference to `err_sys'

please tell me how I must do this

Those error functions are in a libary somewhere. Someone else asked the question about 6 years back here: http://forums.devshed.com/c-programm...p-h-59962.html and appears to have got a success from the answers.

Did you look at the link? If so, what particular bits did you NOT understand? [Note, I have no direct knowledge of how to fix the problem - but the problem appears to have several solutions on the 'Net according to Google - I just posted a link to the first one].
