Is it possible for the 3ds to support flock?

[kaylambdadelta]

I am using the wonderful redb crate and it harmlessly assumes all unix family os's outside of wasi have flock support, which prevents use on the 3ds (missing pieces in libc), is it possible for this to be implemented for the 3ds or what?

The 3DS has no notion of file locking, so I doubt that the flock API could be properly supported. That being said, I took a look at redb's source code and it looks like it has a fallback API that just uses mutexes for file locking. So to me it looks like the best way to add 3DS support to redb would be to make a PR to this file that chooses the fallback impl for the horizon OS instead of using the unix impl.

I see, thank you!
