NdisRawReadPortBufferUlong

This function reads a specified number of ULONGs into a caller-supplied buffer.

At a Glance

Syntax

VOID NdisRawReadPortBufferUlong( IN ULONG Port,
OUT PULONG Buffer, IN ULONG Length );

Parameters

Port

Specifies the I/O port. This address falls in a range that was mapped during initialization with the NdisMRegisterIoPortRange function.

Buffer

Pointer to a caller-allocated buffer, in resident memory, into which the ULONGs are transferred from the NIC. The caller must allocate a buffer at least ( sizeof( ULONG ) * Length ).

Length

Specifies how many ULONGs to transfer from the NIC.

Remarks

This function reads each ULONG value, one at a time, from the given I/O port into the given buffer.

A driver that calls this function can run at any IRQL.
