VOID
NdisZeroMappedMemory(
IN PVOID Destination,
IN ULONG Length
);
NdisZeroMappedMemory fills a block of memory that was mapped with a preceding call to NdisMMapIoSpace with zeros.
Parameters
Destination
Specifies the base virtual address of a block of mapped memory.
Length
Specifies the number of bytes to be filled with zeros.
Comments
A NIC driver can call NdisZeroMappedMemory to zero-initialize mapped device memory. The given Destination and Length must be a proper subrange of the range specified when the driver called NdisMMapIoSpace.
NdisZeroMappedMemory is optimized, and a NIC driver can call this function any time that it needs to clear a mapped memory range.
Callers of NdisZeroMappedMemory can run at any IRQL.
