NdisRawReadPortUshort

VOID
   NdisRawReadPortUshort(
       IN ULONG Port,
       OUT PUSHORT Data
       );

NdisRawReadPortUshort reads a USHORT value from a given 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

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

Comments

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

Callers of NdisRawReadPortUshort can run at any IRQL.
