There are no "the book" and no "the rtos".
If you need help using an RTOS, then you must specify exactly which RTOS you are having problems with. And books are best if written for this specific (RT)OS.
About semaphores etc. The concept is identical for all OS. The API and parameters may vary a bit, but a semaphore works conceptually the same in Windows as it does in any of the RTOS you may be able to find.
