Description
Attempts to acquire a lock on the semaphore.
Data.DBXPlatform.TDBXSemaphore.Acquire inherits from System.SyncObjs.TSemaphore.Acquire. All content below this line refers to System.SyncObjs.TSemaphore.Acquire.
Attempts to acquire a lock on the semaphore.
Call Acquire from the thread that needs to use some of a shared resource's units.
The Acquire method waits until the semaphore becomes free, that is, the number of free units of the resource is nonzero. Then the Acquire method acquires a lock on the semaphore.
If the semaphore is not free, then the calling thread is added to the semaphore waiting queue.
