Best way to read/write a file from a url using C std libs

I'm building a simple C program, which takes a user input parameter (URL) using scanf(), as the code below reflects. I'm now looking for the best "standard" way to read/write the remote file to a local file... which I will then preform a grep (search) operation on the new local source file.

//CODE

#include <stdio.h>

int main(void){
   char url[255];

   //USER INPUT URL
   printf("ENTER URL: ");
   scanf("%s", &url);

   //GET FILE AT URL(REMOTE) AND COPY TO (LOCAL) 




   //RETURN
   return 0;
}
Solution

  • You could use libcurl, or just shell out and use wget or curl, honestly.

    char command[1024];
snprintf(command, 1024, "wget -c '%s'", url);
system(command); // add error handling

    That will take considerably less effort.
