WebGeneral description. Locks a mutex object, which identifies a mutex. Mutexes are used to protect shared resources. If the mutex is already locked by another thread, the thread waits for the mutex to become available. The thread that has locked a mutex becomes its current owner and remains the owner until the same thread has unlocked it. WebThe calling thread locks the mutex, blocking if necessary:. If the mutex isn't currently locked by any thread, the calling thread locks it (from this point, and until its member unlock is called, the thread owns the mutex).; If the mutex is currently locked by another thread, execution of the calling thread is blocked until unlocked by the other thread (other non …
