Directory listing?

[Leo28C]

Hello everyone!

My first post here.

GNU's file management reference isn't clear enough for me:
http://www.delorie.com/gnu/docs/glib...l#SEC_Contents

I get how to recursively get each file/directory name inside a directory, but the question is: how do I get the NUMBER OF files/dirs, so I can allocate an array to store these filenames?

Thanks in advance, people!

(P.S: I'm not coding for Windows, son don't give me Windows API. I'm coding for, guess, what, the Sony PSP. )

At least one example shows how to allocate an expanding array as you go. Perhaps adapt the idea for your own circumstance.

Then you'll need to rummage through the API for that machine then.

Do you need to store ALL filenames, or just some of them?

If you need to store all of them, obviously, you need to use some strategy along the lines of expanding array, or some other dynamic storage method (linked list of a bunch of filenames, perhaps - a linked list of each name may be a bit too much overhead in the form of links and such). What method to use will also depend on what you are planning to do with the files after you've retrieved them from the file-system.

If you need to store only some of them (and there are only really a few) then you may find that a linked list or a static oversized list (e.g. you expect there to be max 50 files, so you make an array that can hold 256 files) is the right approach.

If you use a dynamicly growing array method, make sure you start with a decent size and make sure you grow it in large enough steps, so you don't get too much overhead from copying the content.
