Alertable

Since your thread is in an alertable state, as soon as an APC entry appears, the system wakes your thread and empties the queue (by calling the callback routines).

If you know the HANDLE of a thread you wish to signal, and that thread has performed an alertable wait, then queueing an APC is often significantly quicker than waking the target thread by using kernel objects (as we are about to review).

Every thread has a queue of APCs attached to it, and these are processed when the thread is in an alertable state, such as when they call functions like WaitForSingleObjectEx, WaitForMultipleObjectsEx, and Sleep.

Bids marked in red on the convention card must be alerted. Cue-bids of an opponent's suit, however, are not alertable.

ln general, natural bids are not Alertable.

To alert those calls you may use the alert card in the bidding box or simply say "alert" when partner makes an alertable call.

The whole party, with the concentration of legal ammunition, the relaxed but alertable force of the deputies, weighed heavily against the slight presence of Mr. Grimes sitting beyond the pale, on the silent side of the bar.
