NdisRawReadPortUlong

VOID
NdisRawReadPortUlong(
IN ULONG Port,
OUT PULONG Data
);

NdisRawReadPortUlong reads a ULONG 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 ULONG value read in from the port.

Comments

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.

Callers of NdisRawReadPortUlong can run at any IRQL.
