IDebugDataSpaces3::WriteBusData

-description

The WriteBusData method writes data to a system bus.

-parameters

-param BusDataType [in]

Specifies the bus data type of the bus to write to. For details of allowed values see the documentation for the BUS_DATA_TYPE enumeration in the Microsoft Windows SDK.

-param BusNumber [in]

Specifies the system-assigned number of the bus. This is usually zero, unless the system has more than one bus of the same bus data type.

-param SlotNumber [in]

Specifies the logical slot number on the bus.

-param Offset [in]

Specifies the offset in the bus data to start writing to.

-param Buffer [in]

Specifies the data to write to the bus.

-param BufferSize [in]

Specifies the size in bytes of the buffer Buffer. This is the maximum number of bytes that will be written.

-param BytesWritten [out, optional]

Receives the number of bytes written to the bus. If BytesWritten is NULL, this information is not returned.

-returns

This method can also return error values. See Return Values for more details.

Return code	Description
S_OK	The method was successful.

-remarks

This method is only available in kernel-mode debugging.

The nature of the data read from the bus is system, bus, and slot dependent.
