NdisRawWritePortBufferUshort macro

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

Syntax

void NdisRawWritePortBufferUshort(
   Port,
   Buffer,
   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 USHORTs to be written.

Length

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

Return Value

None

Remarks

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

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