You should store the results of `opendir` into a variable so you can call `closedir` — Chris Turner, May 23 '17 at 16:53

This example works

#include <stdio.h>
#include <dirent.h>

int main(int argc, char ** argv)
{
    DIR *dir;

    dir = opendir("folder");
    if (dir == NULL) {
        printf("Couldn't open dir\n");
    } else {
        printf("Opened dir\n");
    }

    if (dir != NULL)
        closedir(dir);
}
