fopen filename running environment

Using C++ on Windows XP, Windows 7 and Linux.

Reading the fopen documentation (http://www.cplusplus.com/reference/cstdio/fopen/) about filename:

C string containing the name of the file to be opened. Its value shall follow the file name specifications of the running environment and can include a path (if supported by the system).

What does "running environment" mean in this context? The operating system or file systems?

How do I determine what is supported filename for various platforms (without doing trial and error) ?

That means that in Windows you need to specify the path using forward slashes while in Linux/Unix backwards slashes(despite of filesystem type).

Windows example filename: C:/some_path/filename

Unix/Linux/Mac example filename: \some_path\filename

Also means that you can't violate the name spacifications for file names, for instance Windows(NTFS, FAT, ...) don't allow the use of ? caracter while Linux does.

Hence, you can say that "running environment" here refers to both, operating system and file system.
