NdisZeroMappedMemory fills a block of memory that was mapped with a preceding call to NdisMMapIoSpace with zeros.
- Destination [in]
Specifies the base virtual address of a block of mapped memory.
- Length [in]
Specifies the number of bytes to be filled with zeros.
A miniport 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 miniport driver can call this function any time that it needs to clear a mapped memory range.
|Supported for NDIS 6.0 and NDIS 5.1 drivers (see NdisZeroMappedMemory (NDIS 5.1)) in Windows Vista. Supported for NDIS 5.1 drivers (see NdisZeroMappedMemory (NDIS 5.1)) in Windows XP.|
