NdisRawReadPortUshort macro

NdisRawReadPortUshort reads a USHORT value from a given I/O port on the NIC.

Syntax

void NdisRawReadPortUshort(
   Port,
   Data
);

Parameters

Port

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

Data

Pointer to a caller-supplied variable in which this function returns a USHORT value read in from the port.

Return Value

None

Remarks

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