Check if file is a directory

Hello.
I'm having a small problem with a code i'm writing.
I have to read all files in a directory, and, if i find a subdirectory, i have to enter and keep doing operations there.
The problem is I don't know how to determine if the filename is a regular file or a directory.
I am using a struct dirent structure, but i'm on a system which doesn't recognize d_type as a member of this structure.

Any ideas?

Thank you.

First you need to use stat() on your struct dirent variable. Then you can do S_ISDIR(statbuf.st_mode) to see if it's a directory.

Thank you. I didn't know about that.

You could also try access().
