How do I get a list of files in a directory in C++?

Question

How do you get a list of files within a directory so each can be processed?

Answer 1

Here's an example in C on Linux. That's if, you're on Linux and don't mind doing this small bit in ANSI C.

#include 

DIR *dpdf;
struct dirent *epdf;

dpdf = opendir("./");
if (dpdf != NULL){
   while (epdf = readdir(dpdf)){
      printf("Filename: %s",epdf->d_name);
      // std::cout << epdf->d_name << std::endl;
   }
}
closedir(dpdf);
