Hi All,

Just want some links to info on AVStream driver writing (outside of DDK if
anyone knows of some good resources).

Been to WinHec site as well.

Thanks in advance,

Hi All

can any body tell me that what is required to close
a file opened inside the Kernel in a kernel mode driver
using ZwCreateFile . I am doing just a ZwClose for the handle
returned by ZwCreateFIle.

What else is required to close the file as the Softice
shows a resource leak when the driver is stopped

thanks
Mayank

are you opening and closing the file in the context of the same process?
Or did you specify OBJ_KERNEL_HANDLE when you opened the file?
