POSIX Interface

[xxks-kkk]

Vijay: I was thinking about this project, and I realized we need to implement the POSIX interface so that applications can link to our library

One part of the project, perhaps for @danielpygo, could be to create those interfaces/wrappers for POSIX that @xxks-kkk can later implement

I don't think the POSIX API necessarily means a C api
but we do need some way for some target application, lets say the Redis key-value store, can run on our file system
u shud explore how applications can link to a rust library
