Address - the user-provided value that serves as a key.Timeout - an optional pointer to a timeout for the wait. A negative value indicates relative timeout for the specified number of 100-nanosecond intervals. To wait for a specific number of milliseconds, multiply them by -10,000. Positive values indicate an absolute time.STATUS_ALERTED - the thread woke due to a call to NtAlertThreadByThreadId.STATUS_TIMEOUT - the thread woke due to the timeout.Despite the name, the wait this function enters is not alertable and, thus, cannot be interrupted by APCs or NtAlertThread. Alertable waits via NtDelayExecution are unrelated to this functionality.
This function was introduced in Windows 8.
