BUG: DriverCallback Return Value Invalid
The information in this article applies to:
- Microsoft Win32 Device Driver Kit (DDK) Windows 95
DriverCallback returns an invalid value that has nothing to do with the status of the call.
DriverCallback incorrectly overwrites the actual return value right before the function exits.
To work around this problem, do not use the return value as a reference for return status.
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
DriverCallback is a Windows API function that is primarily used by multimedia installable drivers.
