DlSetBusData function (dispmprt.h)

  • Article

Sets bus-configuration data for an adapter on a dynamically configurable I/O bus with a published, standard interface.

Syntax

ULONG DlSetBusData(
  PVOID DeviceHandle,
  ULONG BusDataType,
  ULONG SlotNumber,
  PVOID Buffer,
  ULONG Offset,
  ULONG Length
);

Parameters

DeviceHandle

A handle that represents a display adapter.

BusDataType

Specifies the type of bus data to be set.

SlotNumber

For a BusDataType value that specifies the location of the device on the bus. This parameter should be zero for all other bus types.

Buffer

Pointer to a caller-supplied storage area with configuration information specific to BusDataType.

Offset

Specifies the byte offset within the PCI_COMMON_CONFIG structure at which the caller-supplied configuration values begin. A miniport driver can use PCI_COMMON_HDR_LENGTH to specify the offset of the device-specific area in PCI_COMMON_CONFIG.

Length

Specifies the number of bytes in Buffer.

Return value

This function returns ULONG.
