NdisRawReadPortUlong (NDIS 5.1) function

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

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 faster than NdisImmediateReadPortUlong 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

Desktop
