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.
