NdisRawWritePortBufferUlong

NdisRawWritePortBufferUlong

VOID
   NdisRawWritePortBufferUlong(
       IN ULONG Port,
       IN PULONG Buffer,
       IN ULONG Length
       );

NdisRawWritePortBufferUlong writes a specified number of ULONG values from a caller-supplied buffer to a given I/O port.

Parameters

Port

Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.

Buffer

Points to a caller-allocated resident buffer containing the ULONGs to be written.

Length

Specifies the number of ULONGs to write to the I/O port.

Comments

A NIC driver calls NdisRawWritePortBufferUlong to transfer a sequence of ULONGs, one at a time, to its NIC.

NdisRawWritePortBufferUlong runs significantly faster than NdisImmediateWritePortBufferUlong because it need not map a bus-relative port address onto a host-dependent logical port address at every call.

Callers of NdisRawWritePortBufferUlong can run at any IRQL.
