KeInitializeDpc function (wdm.h)
The KeInitializeDpc routine initializes a DPC object, and registers a CustomDpc routine for that object.
void KeInitializeDpc(
[out] __drv_aliasesMem PRKDPC Dpc,
[in] PKDEFERRED_ROUTINE DeferredRoutine,
[in, optional] __drv_aliasesMem PVOID DeferredContext
);
[out] Dpc
Pointer to a KDPC structure that represents the DPC object to initialize. The caller must allocate storage for the structure from resident memory.
[in] DeferredRoutine
Pointer to the CustomDpc routine to associate with the DPC.
[in, optional] DeferredContext
Specifies the value to pass as the DeferredContext parameter to CustomDpc.
None
The caller can queue an initialized DPC with KeInsertQueueDpc. The caller also can set up a timer object associated with the initialized DPC object and queue the DPC with KeSetTimer.
Storage for the DPC object must be resident: in the device extension of a driver-created device object, in the controller extension of a driver-created controller object, or in nonpaged pool allocated by the caller.
