What is the timing to use semMCreate or semBCreate?

Question

When should I use semMCreate vs. semBCreate? In my opinion, they are both the same.

Answer 1

semMCreate creates a Mutex Semaphore, semBCreate creates a Binary Semaphore, and they are actually quite different.

Very basically: you use the Mutex to protect a critical section of code, and you use a Binary Semaphore to synchronize access to a shared resource. Especially in VxWorks.
