This function registers a network adapter or intermediate driver's Miniport_* entry points and name with the NDIS library when the driver initializes.

NDIS_STATUS NdisMRegisterMiniport(
IN NDIS_HANDLE
NdisWrapperHandle
,
IN PNDIS_MINIPORT_CHARACTERISTICS
MiniportCharacteristics
,
IN UINT
CharacteristicsLength
);

Parameters

NdisWrapperHandle
Handle returned by the NdisMInitializeWrapperfunction.
MiniportCharacteristics
Pointer to an NDIS_MINIPORT_CHARACTERISTICSstructure set up by the caller.

The driver should initialize this structure with 0s before setting up any its members.

CharacteristicsLength
Specifies the length, in bytes, of the caller-supplied characteristics buffer. This parameter must be sizeof(NDIS40_MINIPORT_CHARACTERISTICS ).

The driver includes the build instruction NDIS40_MINIPORT, as appropriate, in its sources; if the driver writer uses the -DNDIS40_MINIPORT compiler switch, this parameter is set when the driver is built.

Return Values

NDIS_STATUS_SUCCESS indicates success. One of the following status values indicates failure:

NDIS_STATUS_BAD_CHARACTERISTICS
The CharacteristicsLengthis too small for the MajorNdisVersionspecified in the buffer at MiniportCharacteristics.
NDIS_STATUS_BAD_VERSION
The MajorNdisVersionor MinorNdisVersionspecified in the characteristics structure is invalid.
NDIS_STATUS_RESOURCES
A shortage of resources, possibly memory, prevented the NDIS library from registering the caller.
NDIS_STATUS_FAILURE
This is a default error status, returned when none of the preceding errors caused the registration to fail. For example, if the NDIS library cannot load the driver's image and lock it into system memory, it returns this error.

Remarks

An network adapter driver calls this function from its DriverEntryfunction after DriverEntrycalls the NdisMInitializeWrapperfunction.

Every network adapter driver that exports only Miniport XXXfunctions must set up a characteristics structure and call this function. This structure is copied in the request to the NDIS library's internal storage. Thus, once it has registered, a miniport driver cannot change its handler functions.

The NDIS library currently does not call MiniportReconfigurefunctions, so such a function in an existing miniport driver does nothing unless the miniport makes internal calls to its MiniportReconfigurefunction from MiniportInitialize.

After the driver has called this function, it should be prepared to be called back at the MiniportInitializeentry point specified in the characteristics structure.

NDIS intermediate drivers, which export both Miniport XXXand Protocol XXXfunctions, usually call the NdisIMRegisterLayeredMiniportfunction, instead of this function. Intermediate drivers that export only a set of Miniport XXXfunctions usually call this function.
