NdisRawReadPortUshort function

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

Syntax


VOID NdisRawReadPortUshort(
  _In_   ULONG_PTR Port,
  _Out_  PUSHORT Data
);

Parameters

Port [in]

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

Data [out]

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.
