Not in any CRT implementation that I’ve ever seen. It is useless info, you already have to supply the file name to get a FILE*. You could probably dig an operating system handle out of the FILE structure although you might need to hop through a file descriptor table. Your next problem is then the operating system support you’d need to map a file handle back to a file name. That should be difficult too.
