Are Textbook Implementations a Valid Reference for Assignments?

When reading over the textbook there is pretty specific implementations in the book that relate to our assignment.

I have already completed 99% of the assignment and do not need the book as what it offers I have completed however, I was wondering are those specific implementations fair game when it comes to the assignments in the future or should I avoid looking at the specifications in the book in regards to academic integrity / original ideas.

What specifically is in the book?

I didn’t look through the book at locks or cvs but there is an implementation on the dining philosophers problem which can be used to help for synchprobs and there is also a discussion about many readers / writers which pretty much gives the implementation of rwlocks without starvation control.

That sounds OK to me. Starvation is really the hard part of RW locks.
