NdisRawReadPortUlong macro

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

Syntax

void NdisRawReadPortUlong(
   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 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.
