VOID
NdisZeroMemory(
IN PVOID Destination,
IN ULONG Length
);
NdisZeroMemory fills a block of memory with zeros.
NdisZeroMemory fills the specified range with zeros. The given Destination and Length must be a proper subrange of a caller-accessible memory range.
As long as the given range was allocated from nonpaged pool, the caller can be running at any IRQL. Otherwise, a caller must be running at IRQL < DISPATCH_LEVEL as, for example, when a caller clears a structure it allocated on the stack.
