RtnSetDataLong

RtnSetDataLong sets the value at offset index of the network device pointed to by ndp. RtnSetDataLong and RtnGetDataLong allow the driver writer to save driver specific data in the network device data structure.

Syntax

VOID RtnSetDataLong(
    PVOID ndp,
    LONG offset,
    ULONG data
);

Parameters

ndp

Network Device Pointer. Opaque network device identifier (pointer).

offset

Offset of data to set.

data

Data to set in the ndp structure

Return Value

None

Remarks

The number of data elements is application-specific. The TCP/IP Stack uses 4 data elements.

RtnSetDataLong must be used to store the index the local configuration data structure into the ndp structure for use in the rest of the driver. This is usually done at the top of the RtndConfigure routine.

Data offset 0 is used to store this index.

Offset 1 is used by the NAL to store the device queue number.

Offset 2 is used by the TCP/IP Stack.
