Thread: c programming http get request

Hello,
I am trying to work out how to write a web server program that will serve a single file via a HTTP GET request if the file exists otherwise give the user a 404 error.

I have started by figuring out what libraries I would need, the size of the buffer and a basic struct

Code:

#include <stdio.h>
#include <stdlib.h>
    #include <unistd.h>
    #include <errno.h>
    #include <string.h>
    #include <fcntl.h>
    #include <signal.h>
    #include <sys/types.h>
    #include <sys/socket.h>
    #include <netinet/in.h>
    #include <arpa/inet.h>
#define BUFZ 8096;
struct
    {
       char *file_type;
       char *ext;
       
    }
    extensions [] =
    {
       {"gif", "image/gif" }, 
       {"jpg", "image/jpeg"},
       {"jpeg","image/jpeg"},
       {"png", "image/png" },   
       {"htm", "text/html" }, 
       {"html","text/html" }, 
       {0,0}
    };

I am not sure exactly where to take it from here. I am trying to get the web server to listen on port 10076 and requests should be outputted in the browser, through the network card ie the request would be http://ipofethcard:10076/path/file.html

Any ideas on how to achieve this or what functions I would need to look at? Perhaps an example code/skeleton I could refer to?

Thanks for any suggestions,
