NdisRawWritePortUchar macro

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

Syntax

void NdisRawWritePortUchar(
   Port,
   Data
);

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.

Return Value

None

Remarks

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