NdisRawWritePortUchar (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 x has been deprecated and is superseded by NDIS 6.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.

NdisRawWritePortUchar writes a byte to an I/O port on the NIC.

Syntax


VOID NdisRawWritePortUchar(
  _In_ ULONG_PTR Port,
  _In_ UCHAR     Data
);

Parameters

Port [in]

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

Data [in]

Specifies the byte to be written.

Return value

None

Remarks

NdisRawWritePortUchar runs faster than NdisImmediateWritePortUchar because it need not map a bus-relative I/O port address onto a host-dependent logical port address at every call.

Requirements

Target platform

Desktop
