this calls for a switch()

opendir can return 0, in which case the next line will probably crash.

Overall, this whole method seriously lacks error handling in my opinion. Just checking for errno at the end isn't enough, e.g. in cases like this where multiple calls are being made.

And even otherwise, I'm unsure if ignoring the return value of chmod/chown/unlink/mkdir and *just* checking errno is enough or not. Does anyone else know?

should be FILEHELPER_H to match the filename

This isn't public API -> no @since.
