NdisRawWritePortBufferUshort (NDIS 5.1) function
Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.
NdisRawWritePortBufferUshort writes a specified number of USHORT values from a caller-supplied buffer to a given I/O port.
Syntax
VOID NdisRawWritePortBufferUshort(
_In_ ULONG_PTR Port,
_In_ PUSHORT Buffer,
_In_ ULONG Length
);
Parameters
Port [in]
Specifies the I/O port. This address falls in a range that was mapped during initialization with NdisMRegisterIoPortRange.Buffer [in]
Pointer to a caller-allocated resident buffer containing the USHORTs to be written.Length [in]
Specifies the number of USHORTs to write to the I/O port.
Return value
None
Remarks
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.
