unistd.h implementation

Question

My toolchain (Realview) does not have implementation of unistd.h , I have a code that I need to use that is using unistd.h , some function like access , open .

So I need to implement this functions by myself.

My question is, is there another alternative or some reference (except the function description, found here ) that I can use in order to port/implement these functions?

What is the correct way to do that? It's my first time posting.

Answer 1

The "function description" you link to has the page title "The Open Group Base Specifications Issue 6", which indicates that it's perhaps a bit more of a heavy-weight than just being a mere description.

If you implement a function that fulfills all the text on that page correctly, chances are you've managed to re-implement it in a compatible way, so that programs complying to the same standard will build and work.

Not sure what else you feel you would need.
