NdisRawWritePortUchar

VOID
    NdisRawWritePortUchar(
        IN ULONG Port,
        IN UCHAR Data
        );

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

Parameters

Port

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

Data

Specifies the byte to be written.

Comments

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.

Callers of NdisRawWritePortUchar can run at any IRQL.
