program to validate directory name
I just want to write a program which takes a directory name as argument

- Validate that it is in fact a directory
- Get a listing of all files in the directory and print it
The word directory doesn't even appear in the C standard. This is an OS concept.
Look at stat. It will provide you with the information you want; all you have to do is interpret it.
Edit: A brief example.
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdio.h>
#define TRUE 1
#define FALSE 0
int is_dir(char *path)
{
struct stat dir_stats;
stat(path, &dir_stats);
if (S_ISDIR(dir_stats.st_mode))
return TRUE;
return FALSE;
}
For the list of files in the directory, use readdir.
