NdisRawWritePortBufferUshort macro (ndis.h)

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

Syntax

void NdisRawWritePortBufferUshort(
  [in]  Port,
  [in]  Buffer,
  [in]  Length
);

Parameters

[in] Port

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

[in] Buffer

Pointer to a caller-allocated resident buffer containing the USHORTs to be written.

[in] 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.
