PRB: DDK: First Argument Passed to the Callback Function May Become Null

 * }

Q299301

-

The information in this article applies to:


 * Microsoft Windows 2000 Driver Development Kit (DDK)

-

SYMPTOMS
When the required Callback function is called in the PsSetLoadImageNotifyRoutine, the first argument passed to the Callback function may become a NULL pointer.

STATUS
This behavior is by design.

MORE INFORMATION
When you register the Callback routine, keep in mind that NULL may be passed as the first argument.

The first argument is obtained from the file object pointer in the member of the section object. This pointer is to be NULL unless it stores a file handle to the argument when it creates a section.
