How can I get the list of files in a directory using C or C++?

Question

How can I determine the list of files in a directory from inside my C or C++ code? I'm not allowed to execute the `ls` command and parse the results from within my program.

Answer 1

#include <stdio.h>

#include <dirent.h>

#include <sys/types.h>

static void list_dir(const char *path)

{

struct dirent *entry;

DIR *dir = opendir(path);

if (dir == NULL) {

return;

}

while ((entry = readdir(dir)) != NULL)

{

printf("%s\n",entry->d_name);

}

closedir(dir);

}

int main()

{

list_dir("C:\\windows");

}
