NdisRawReadPortUlong function

NdisRawReadPortUlong reads a ULONG value from a given I/O port on the NIC.

Syntax


VOID NdisRawReadPortUlong(
  _In_  ULONG_PTR Port,
  _Out_ PULONG    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 ULONG value read in from the port.

Return value

None

Remarks

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

Requirements

Target platform

Universal

Version

Supported for NDIS 6.0 and NDIS 5.1 drivers (see NdisRawReadPortUlong (NDIS 5.1)) in Windows Vista. Supported for NDIS 5.1 drivers (see NdisRawReadPortUlong (NDIS 5.1)) in Windows XP.
