    How to get names to all files/folders in a folder?

    Hi all!
    I am quite new to ANSI C so here comes a newbee question:
    How to get names to all files/folders in a folder without knowing their names?
    fopen() workes fine when you know the name of the file.
    As far as I have found out this isn't supported in the library but what is the way to solve it?

    Many thanks

    I don't know of a standard way of doing that. These seems more like a script kind of thing. Why do you want to do this ?

    I think the library you need is dirent.h
    this will give you functions like opendir() and readdir()
    You might also need sys/stat.h for stat()

    I have got an application that in a specific situation produces files in a folder and will not stop untill hd is full ( a bugg ofcause) but til the owner of that software has fixed the bugg I want to write a small app that checkes the folder and if it is not empty delete all files. That is why I want to find a way to "browse" a folder and I can imagine that there are more situations that you are interested in finding out the contents of a folder.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    There's always the FAQ...

    But if all you're interested in is deleting all the files in a given folder, then a 1-line command file will do the trick.

    You can even schedule it to do it automatically.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
