The producer produces items and adds them to the buffer, while the consumer consumes items from the buffer. Semaphores are synchronization primitives that can be used to solve this problem efficiently ...
One way to achieve this synchronization is by using semaphores, which are special variables that can be incremented or decremented atomically. In this article, you will learn how to use semaphores ...
ThreadX provides 32-bit counting semaphores with counts that range in value from 0 to 2 32 1, or 4,294,967,295 (inclusive). There are two operations that affect the values of counting semaphores: ...
The mutex primitive provides mutual exclusion for one or more data objects. Two versions of the mutex primitive are provided: spin mutexes and sleep mutexes. Spin mutexes are a simple spin lock. If ...
If the system has this parameter (many do not), it defines the size of the semaphore resource map, in which each contiguous block of available semaphores needs an entry. When a semaphore set is freed ...

Whether right or wrong is there a good doc to refer to get a good understanding of best practices. Have you read the Semaphores chapter of the SYS/BIOS User's Guide? Note that in the intro to the ...
A fundamental overview of operating systems (OSes) with an emphasis on practice. Topics covered include: OS structure, OS models, OS abstractions, concurrency sources, concurrency challenges, ...
