A '''mutex''' (''abbreviated'' '''Mut'''ually '''Ex'''clusive access) is a synchronization object, a variant of [[semaphore]] with ''k''=1.
A '''mutex''' (from "'''mut'''ual '''ex'''clusion") is a synchronization object, a variant of [[semaphore]] with ''k''=1.
A mutex is said to be seized by a [[task]] decreasing ''k''.
It is released when the task restores ''k''. Mutexes are typically used to protect a shared resource from concurrent access.
A [[task]] seizes (or acquires) the mutex, then accesses the resource, and after that releases the mutex.
