EX_TIMER structure

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;

Members

All members of this structure are opaque to drivers.

Remarks

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.

For more information, see ExXxxTimer Routines and EX_TIMER Objects.

Requirements

Version

Supported starting with Windows 8.1.
