Searching files in folder

[Steffen Loringer]

Hi group,

may be a simple question: How can I find out in C, which files of a
specified extension exist in a specified folder? My app should
constantly look for a file with an known extension but unknown name. A
link with an example would be nice

Thanks a lot for help

It really depends on what platform you're coding for.

On windows, take a look at FindFirst and FindNext APIs

You can't in standard C. You will have to ask in a group dedicated to
your platform for the platform specific extensions (if they exist) that
will allow you to do this.

On some systems there are far better ways than continually looking for
the files, on other systems you will have to continually read the
directory, and on some systems files don't even *have* extensions.

The is no standard C answer. However, opendir() readdir() is POSIX.1
hence available on many platforms.
