Thread: Client/Server Programming!!!

Hi,
I want to build a client/server chat program for the dos environment. I have no idea about socket programming. Is there any tutorial which can help me in this? Any website which explains this?

Check out these include files.

#include <sys/socket.h>
#include <netinet/in.h>

You may want to really look at this structure.

struct sockaddr_in servaddr;

Code:

/* create socket, quit if error */
	if ( (sockfd = socket(AF_INET,SOCK_STREAM,0)) <  0) {
		printf("socket error.\n");
		exit(0);
	}

	/* servaddr values */
	bzero(&servaddr, sizeof(servaddr));
	servaddr.sin_family = AF_INET;
	servaddr.sin_port = htons(atoi(argv[2])); 
	servaddr.sin_addr.s_addr = inet_addr(argv[1]);
	

	/* connect to server, quit if error */
	if(connect(sockfd, (SA *) &servaddr, sizeof(servaddr)) < 0) {
		printf("did not connect!\n");
		exit(0);
	} else
		printf("connected!\n");

    
	/* Send message to server */
	write(sockfd, serverMessage, strlen(serverMessage));
