NdisRawWritePortUlong

VOID
NdisRawWritePortUlong(
IN ULONG Port,
IN ULONG Data
);

NdisRawWritePortUlong writes a ULONG value to an 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

Specifies the ULONG to be written.

Comments

NdisRawWritePortUlong runs faster than NdisImmediateWritePortUlong because it need not map a bus-relative I/O port address onto a host-dependent logical port address at every call.

Callers of NdisRawWritePortUlong can run at any IRQL.
