NdisRawWritePortBufferUshort

VOID
   NdisRawWritePortBufferUshort(
       IN ULONG Port,
       IN PUSHORT Buffer,
       IN ULONG Length
       );

NdisRawWritePortBufferUshort writes a specified number of USHORT 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 USHORTs to be written.

Length

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

Comments

A NIC driver calls NdisRawWritePortBufferUshort to transfer a sequence of USHORTs, one at a time, to its NIC.

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

Callers of NdisRawWritePortBufferUshort can run at any IRQL.
