The EX_TIMER structure is an opaque structure that is used by the operating system to represent an EX_TIMER timer object.
typedef struct _EX_TIMER *PEX_TIMER;
All members of this structure are opaque to drivers.
The following ExXxxTimer routines require a pointer to a system-allocated EX_TIMER structure as an input parameter:
EX_TIMER-based timer objects are created by the operating system. To get such a timer object, your driver calls the ExAllocateTimer routine. When this object is no longer needed, the driver is responsible for deleting the object by calling ExDeleteTimer.
