getting strings for all the files and folders in a folder

Hard_Working_ · 04-06-2007, 02:30 AM

Hi everyone:

I need to list all the files and folders that exists in a folder. Just like the LS function, however I need to do this is c++, without doing system calls.

What I actually need is to find a way to get into an array of strings, the name of each file and folder inside a certain folder.

Any idea how to do this?

Thank you

Do you mean without the system() call or without system calls? I suspect you mean the first one.
In that case, see "man readdir".

I meant without doing any type system calls, my teacher wants me to implement the typical shell commands in c ++, without actually calling them, if I used them, then i would be cheating...

Anyway, thanks for your help, your suggestion works fine.

I don't know exactly:

but I guess , you can do them using disk driver ;
if you write disk driver by yourself, then there is no systemcall,
