The ObIsKernelHandle routine determines whether the specified handle is a kernel handle.
Syntax
BOOLEAN ObIsKernelHandle(
[in] HANDLE Handle
);
Parameters
[in] Handle
The handle to check.
Return value
ObIsKernelHandle returns TRUE if Handle is a kernel handle and FALSE otherwise.
Remarks
You can use kernel handles only in kernel mode. A driver can mark a handle as a kernel handle by specifying the OBJ_KERNEL_HANDLE flag in OBJECT_ATTRIBUTES when it creates the handle.
Note ObIsKernelHandle does not verify that the parameter is a valid handle. This routine only determines if a valid handle is a kernel handle. If the parameter is not a valid handle, the result of the routine is undefined.
