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.
