Hello friends,
I have a problem on transfering a .html file from client to server.
Earlier I have done two program, one for client and another for server only for message passing in Linux(RED HAT ENTERPRISE LINUX V4).

client program is:

---------------------------------------------------------------------------------------

#include <stdio.h>

#include <sys/types.h>

#include <sys/socket.h>

#include <netinet/in.h>

#include <netdb.h>


void error(char *msg)

{

perror(msg);

exit(0);

}



int main(int argc, char *argv[])

{

int sockfd, portno, n;

struct sockaddr_in serv_addr;

struct hostent *server;


char buffer[256];

if (argc < 3)
{

fprintf(stderr,"usage %s hostname port\n", argv[0]);

exit(0);

}

portno = atoi(argv[2]);

sockfd = socket(AF_INET, SOCK_STREAM, 0);

if (sockfd < 0)

error("ERROR opening socket");

server = gethostbyname(argv[1]);

if (server == NULL)
{

fprintf(stderr,"ERROR, no such host\n");

exit(0);

}


bzero((char *) &serv_addr, sizeof(serv_addr));

serv_addr.sin_family = AF_INET;

bcopy((char *)server->h_addr,
(char *)&serv_addr.sin_addr.s_addr,
server->h_length);

serv_addr.sin_port = htons(portno);

if (connect(sockfd,(struct sockaddr *) &serv_addr,sizeof(serv_addr)) < 0)
error("ERROR connecting");
printf("Please enter the message: ");

bzero(buffer,256);

fgets(buffer,255,stdin);

n = write(sockfd,buffer,strlen(buffer));

if (n < 0)

error("ERROR writing to socket");

bzero(buffer,256);

n = read(sockfd,buffer,255);

if (n < 0)

error("ERROR reading from socket");

printf("%s\n",buffer);

return 0;

}
-----------------------------------------------------------------------------------

server program is:

/* A simple server in the internet domain using TCP
The port number is passed as an argument
This version runs forever, forking off a separate
process for each connection
*/
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>

void dostuff(int); /* function prototype */
void error(char *msg)
{
perror(msg);
exit(1);
}

int main(int argc, char *argv[])
{
int sockfd, newsockfd, portno, clilen, pid;
struct sockaddr_in serv_addr, cli_addr;

if (argc < 2) {
fprintf(stderr,"ERROR, no port provided\n");
exit(1);
}
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0)
error("ERROR opening socket");
bzero((char *) &serv_addr, sizeof(serv_addr));
portno = atoi(argv[1]);
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = INADDR_ANY;
serv_addr.sin_port = htons(portno);
if (bind(sockfd, (struct sockaddr *) &serv_addr,
sizeof(serv_addr)) < 0)
error("ERROR on binding");
listen(sockfd,5);
clilen = sizeof(cli_addr);
while (1) {
newsockfd = accept(sockfd,
(struct sockaddr *) &cli_addr, &clilen);
if (newsockfd < 0)
error("ERROR on accept");
pid = fork();
if (pid < 0)
error("ERROR on fork");
if (pid == 0) {
close(sockfd);
dostuff(newsockfd);
exit(0);
}
else close(newsockfd);
} /* end of while */
return 0; /* we never get here */
}

/******** DOSTUFF() *********************
There is a separate instance of this function
for each connection. It handles all communication
once a connnection has been established.
*****************************************/
void dostuff (int sock)
{
int n;
char buffer[256];

bzero(buffer,256);
n = read(sock,buffer,255);
if (n < 0) error("ERROR reading from socket");
printf("Here is the message: %s\n",buffer);
n = write(sock,"I got your message",18);
if (n < 0) error("ERROR writing to socket");
}

Now I want to do two programs,for transferring of .html file from client to server and found difficult because I wrote all the codes for linux and those header files are not supported by VC++ compiler.
Can anyone help me out from this problem?If someone give the apropriate code for those two programs then it will be better.
I will always grateful to him/her.
