NdisRawWritePortBufferUlong

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

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

Parameters

Port

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

Buffer

Pointer 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.

Headers

Declared in Ndis.h. Include Ndis.h.

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.
