Listing hidden files

I'm writing a c program to list the files in a given directory but I also want to display the hidden files. I can't figure this out in c. Does anyone know how to do this? Here's the code I have so far:

Code:

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

void printdir( char *dir, int depth );

int main( int argc, char *argv[ ] )
{
	printf( "\n\nDirectory scan of %s\n", argv[1] );
	printdir( argv[1], 0 );
	printf( "done.\n");
	
	return 0;
}

void printdir( char *dir, int depth )
{
	DIR *dp;
	struct dirent *entry;
	struct stat statbuf;
	
	if( ( dp = opendir( dir ) ) == NULL )
	{
		perror( "Cannot open directory:\n" );
		return;
	}
	
	chdir( dir );
	
	while( ( entry = readdir( dp )) != NULL )
	{
		lstat( entry->d_name, &statbuf );
		
		if( S_ISDIR( statbuf.st_mode) )
		{
			if( strcmp( ".", entry->d_name ) == 0 || strcmp( "..", entry->d_name ) == 0 )
			{
				continue;
			}

			printf( "%*s%s/\n", depth, "", entry->d_name );
			printdir( entry->d_name, depth+4 );
		}
		else
		{
			printf( "%*s%s\n", depth, "", entry->d_name );
		}
	}
	
	chdir( ".." );
	closedir( dp );
}

NAME

       dirent.h, dirent - format of directory entries

SYNOPSIS

       #include <dirent.h>

DESCRIPTION

       The internal format of directories is unspecified. The <dirent.h> header defines the following type:

       DIR             A type representing a directory stream.

       The header also defines the structure dirent, which includes the following members:

       ino_t d_ino        /* file serial number */
       char  d_name[]     /* name of entry */

       The type ino_t is defined as described in <sys/types.h>. See types(3HEAD).

       The character array d_name is of unspecified size, but the number of bytes preceding the terminating null byte must not exceed {NAME_MAX}.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE         |      ATTRIBUTE VALUE        |
