Return an odd value if this semaphore is wait disabled, and an even value otherwise. The returned value can be used to detect a rapid short sequence of disable and enable invocations by comparing the value returned by getDisabledState before and after the sequence. For example, for any initial state of a semphore instance obj: ` int state = obj.getDisabledState(); obj.disable(); obj.enable(); ASSERT(state != obj.getDisabledState()); ` This functionality is useful in higher‐level components to determine if this semaphore was disabled during an operation.
