VideoPortScanRom function (video.h)

The VideoPortScanRom function is obsolete in Windows XP and later versions. It is supported only for backward compatibility.

VideoPortScanRom performs a case-sensitive search for a specified string in ROM.

Syntax

VIDEOPORT_DEPRECATED VIDEOPORT_API BOOLEAN VideoPortScanRom(
  PVOID  HwDeviceExtension,
  PUCHAR RomBase,
  ULONG  RomLength,
  PUCHAR String
);

HwDeviceExtension

Pointer to the miniport driver's device extension.

RomBase

Specifies the base ROM address at which the search should start. The given RomBase must be in a mapped range returned by VideoPortGetDeviceBase.

RomLength

Specifies the size in bytes of the mapped ROM to be searched.

String

Pointer to the driver-allocated string to search for.

If the string is found, VideoPortScanRom returns TRUE. Otherwise, it returns FALSE.

VideoPortScanRom cannot be called from a miniport driver's HwVidInterrupt or HwVidTimer functions, or from VideoPortQueueDpc, or from a callback to VideoPortSynchronizeExecution.
