    readdir() is a posix (linux/unix) function. It doesn't exist in Windows. There is, instead, FindFirstFile, FindNextFile and FindClose.

    Here's the help on FindFirstFile, the rest are documented in links from this page:

    You can also have a look in the FAQ, which has code that reads a directory in Windows (as well as Posix type systems).

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    Windows is more screwed up than you'd think, half-ass POSIX compliant (that's an oxymoron!). Then they decided to ditch it, then not, then, then not, then, then not...

    It did exist, however it seems to have been erased -- they seem to try and abstract themselves as far away from unix as possible.

    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.
