How can I list the whole file in a directory in POSIX / c C ++?

I need to list the entire file in a directory, and then go to the subdirectory and do the same.

Ideally, the algorithm should work in the same way on linux macos [windows (outdated) no more].

UPDATE: I now know VFS, but I'm puzzled by using VFS to list dir. Any suggestion? Should I open the directory as a file?

POSIX.1-2001 specifies opendir, readdirand closedir, seekdir, rewinddirand telldir. Your platform probably contains man pages describing how to use them.
