RussianQuestion
Is there a way to read file names from a folder using purely C (or C++)? That means without including windows.h (no FindFirstFile(), etc...).
It doesn't look like fstream has this functionality. I know that file names are operating system dependent, but I was hoping there is some library that will allow it in Windows.
Solution
boost filesystem is a nice solution. Of course under the hood, it will still be using the windows API calls (when you build on windows), but this is abstracted away from you.
OTHER TIPS
C++ typically does not supply you with such functionality. A cross-platform solution is to use boost::filesystem.
Try the POSIX functions opendir() and readdir() for iterating through directories. See this link for the manual page with some great example code. These functions should be available on most platforms, both Windows and UNIX.
If you wish to use opendir() and readdir() on windows, you can download MinGW, a windows port of the famous GNU compiler collection. It includes windows ports of the UNIX header files, including dirent.h, which will allow you to use the specified functions. Keep in mind these will call native API's either way.
