How to use files in a path?

guriwashere · 06-07-2009, 05:13 PM

Hi, I need some help with a program.
The thing is that I can't find a function to do the following,

For example:

I have 1.txt, 2.txt, 3.txt in C:\files

And I need to work with those files with a program, but i don't know how to read the path and save the file names in an array or something, to use them later.

Anyone please help!

Thanks!!

Read the path from where?

A function or something...

The main thing is to save the file names in an array or buffer...

But it has to be available to the program somehow. So it's either hard-coded in the source or supplied on stdin.

Yes, but read the path from where? A file? Hardcoded into your program? Something the user types in? An open file dialog?

Hardcoded into the program

To read always from the same path.

Thanks!

Then you just have to type the path into your program, like

Code:

const char *filenames[] = {"path\\1", "path\\2"};

You need to use two backslashes to get a literal backslash into your string.

But the thing is that I won't always know the names of the files, so I need to read all of them, and save the names in an array to use them.

But where are you planning to read them from? Do you intend to do a dir/ls/moral equivalent to get a list of the files in the directory, or what?

YES, I need to do a list of the files in a path, and save them in an array.

I don't care how to do it, I just need that.

You are interested in the functions opendir(), readdir(), and closedir()

No one could have ever asked that before, surely. Have you searched the boards? Even better, have you searched the FAQs?

So the path is known? Ie, you could hardcode the path:

Code:

path[]="/some/place/";

Read up on opendir(). You can use that to create an array of files in the directory.

If you have to recurse into the tree, that is more work.
