Hello all, I was wondering how you use the FS resources (not just functions, but defines and typedefs/structs as well) in coreinit.rpl to read from/write to files?

You can't use any typedef or structs because they are not compiled. You have to reverse engineer them or just copy them from existing projects or e.g. wiiubrew.org. The FS functions can be used but they are kinda "hard to use" because of how many things you need to take care of. See this for examples on how they can be used: https://github.com/dimok789/ddd and https://github.com/BullyWiiPlaza/tcpgecko.

I'd recommend taking a look at https://github.com/decaf-emu/wut/blob/master/src/crt/fs_dev.c#L116 and the other functions, it's the actual devoptab for wut so you can see what you'd need to replicate an fopen -> fwrite/fread -> fclose. Basic gist though is that you have an FSClient instance and FSCmdBlock structures. I think w/ FSCmdBlock you can technically queue up operations and have them done asynchronously, but as far as the underlying structures I don't think it matters as much as long as you're passing the right arguments around and your allocation sizes are sane.
