    windows network programming noob question

    Hey all,
    I am trying to learn network programming but in a very simple form. I looked at it a bit in linux and it made sense but i want it to work in windows. Here is my code. I am getting a error when trying to bind the socket. I'm using dev C++

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <windows.h>
    #include <winsock.h>
    
    int main()
    {
      int socket_desc;
      struct sockaddr_in address;
      int addrlen;
      int new_socket;
    
      if ((socket_desc=socket(AF_INET,SOCK_STREAM,0))==0)
      {
        perror("Create socket");
        exit(EXIT_FAILURE);
      }
    
      address.sin_family = AF_INET;
      address.sin_addr.s_addr = INADDR_ANY;
      address.sin_port = htons(33440);
      
      if (bind(socket_desc,(struct sockaddr *)&address,sizeof(address)) == -1)
      {
        perror("bind");
        exit(EXIT_FAILURE);
      }
    
      if (listen(socket_desc,3)<0)
      {
        perror("listen");
        exit(EXIT_FAILURE);
      }
    
      addrlen=sizeof(address);
      if ((new_socket=accept(socket_desc,(struct sockaddr *)&address,&addrlen))<0)
      {
        perror("accept");
        exit(EXIT_FAILURE);
      }
      printf("New socket is %d\n",new_socket);
    
      sleep(10);
    
      close(socket_desc);
    }
    -- Will you show me how to c++?

    The errors from my Dev-C++ state:

    sleep is undeclared
    close is undeclared

    sleep is called Sleep() in Windows [and you probably want to put 10000 as the parameter, as Unix sleep takes a time in seconds, whilst Sleep takes millisecond times], and you probably want to use closesocket() rather than close().

    You also need to use WSAStartup().

    You also need to work on your communication skills to get effective help. Here are a couple of specific hints:

    -- You should have relayed your actual errors in your first post.
    -- You should have relayed that you were unable to compile and/or link the program. You see, your initial message would seem to indicate that you were successful in compiling and running the program.
    -- Don't give false information. Your initial message would lead us to believe that you were receiving an error from the perror call following the failed bind. In fact, this problem has absolutely nothing to do with bind. When in doubt, just give the facts...all the facts you are able.

    Hey, sorry for the confusion. The error i was getting was during run time when trying to bind the socket. But i figured out the problem and it was indeed the WSAStartup().
