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.
