This two-part series addresses the use and misuse of two of the most essential synchronization primitives in modern embedded systems, the mutex (this part) and the semaphore (part 2). Mutexes and ...

Learn the core concepts of thread synchronization used to build multi-threaded .NET applications that enforce thread safety and avoid deadlocks. The C# programming language has provided support for ...

A thread of execution is a set of instructions that are managed by a scheduler. If you make a new thread separate from your program’s main thread, a new independent execution flow will be added to ...

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: ...
