FastPostSemaphore [constructor] | Constructors |
clockType | Return the clock type used for timeouts. |
disable | Disable waiting on this semaphore. |
enable | Enable waiting on this semaphore. If the semaphore is not disabled, this call has no effect. |
getDisabledState | Return an odd value if this semaphore is wait disabled, and an even value otherwise. |
getValue | Return the current value (count > 0 ? count : 0) of this semaphore. |
isDisabled | Return true if this semaphore is wait disabled, and false otherwise. Note that the semaphore is created in the "wait enabled" state. |
post | post overloads |
postWithRedundantSignal | Atomically increase the count of this semaphore by the specified value. |
take | Take up to maximumToTake units from this semaphore. |
takeAll | If the count of this semaphore is positive, reduce the count to 0 and return the original value of the count. Otherwise, do nothing and return 0. |
timedWait | Block until this semaphore can be acquired or absTime expires. |
tryWait | Attempt to decrement this semaphore's count without blocking. |
wait | Block until this semaphore's count is positive, then decrement it. |
