DOC: Incorrect Return Value for HalGetBusData (PCI)

• Microsoft Win32 Device Driver Kit (DDK) for Windows NT, version 3.5

SUMMARY

The Win32 DDK version 3.5 online documentation incorrectly states that the HalGetBusData return value to indicate an error on a PCI bus will be either 0 (zero) or 4. An error is actually indicated by either a 0 (zero) or 2.

The return value of 0 (zero) indicates that the PCI bus does not exist.

The return value of 2 indicates that the PCI bus exists, but there is no device at the specified slot number. The parameter "Buffer" also contains the value PCI_INVALID_VENDORID at the PCI_COMMON_CONFIG VendorID member.

This documentation error is corrected in the Win32 DDK version 3.51 online documentation.
