Hi arijit_rebaca,

Perhaps it should be:

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

:-)

manish_regmi

also, do NOT use #include <bits/dirent.h> directly.
It is unportable. dirent.h is enough

Little modification ...just try this.

#include <dirent.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
#include <dirent.h>

int main()
{

DIR *dp;
struct dirent *drp;
struct stat buf;

/* open the current working driectory */
if((dp = opendir(".")) == NULL) {
perror("opendir");
exit(1);
}

while (drp = readdir(dp)) {
if (stat(drp->d_name,&buf) == 0)
if(buf.st_mode & S_IFDIR)
printf("%s\n", drp->d_name);
}
return closedir(dirp);
}
