opendir() + customly created directories

Gday all

In a program I am designing, I am using opendir() to test whether entries under a certain directory are sub-directories or not. This method works fine for the directory itself (.) and the parent directory (..), however it does not work for any sub-directories I manually create.

i.e. it does not work for current_directory/my_sub_directory

I am performing the test in the following manner

Code:
if( (sub_dir = opendir(sub_dir_name)) != NULL)
{
       /* Do whatever*/

}

Is there anything I am failing to understand or am I missing out on anything ?

regards
James
