VOID VideoPortStopTimer(
| PVOID HwDeviceExtension | |
| ); |
VideoPortStopTimer disables calls to a miniport’s HwVidTimer function.
Parameters
HwDeviceExtension
Points to the miniport driver’s device extension. This pointer is the input parameter to the HwVidTimer function.
Comments
VideoPortStopTimer is called to disable the miniport’s HwVidTimer function. After a miniport driver calls VideoPortStartTimer, its HwVidTimer function is called periodically at approximate one-second intervals until the driver calls VideoPortStopTimer.
A miniport driver cannot call VideoPortStartTimer or VideoPortStopTimer if its DriverEntry function set the HwTimer member of the VIDEO_HW_INITIALIZATION_DATA structure to NULL.
A miniport’s HwVidTimer function can call VideoPortStopTimer.
