Sets bus-configuration data for a device on a PCI bus.

ULONG RtSetBusDataByOffset(
    BUS_DATA_TYPE BusDataType,
    ULONG BusNumber,
    ULONG SlotNumber,
    PVOID pBuffer,
    ULONG Offset,
    ULONG Length
);

Parameters

BusDataType
Type of bus data to set. Currently, its value can be only PCIConfiguration.
BusNumber
Zero-based number of the bus in the system.
SlotNumber
Logical slot number.
pBuffer
Pointer to a caller-supplied buffer that contains configuration data. Since currently only PCI configuration data can be obtained, the buffer contains all or part of the PCI_COMMON_CONFIG data type.
Offset
Offset in PCI_COMMON_CONFIG that indicates where to start writing.
Length
Number of bytes to write.

Remarks

Only PCI configuration data can be set.

Return Values
