NdisIfRegisterProvider (Compact 2013)

This function registers an NDIS network interface provider.

Syntax

NDIS_STATUS
  NdisIfRegisterProvider(
    IN PNDIS_IF_PROVIDER_CHARACTERISTICS  ProviderCharacteristics,
    IN NDIS_HANDLE  IfProviderContext,
    OUT PNDIS_HANDLE  pNdisProviderHandle
    );

Parameters

  • ProviderCharacteristics
    A pointer to a caller-provided NDIS_IF_PROVIDER_CHARACTERISTICS structure. This structure defines the characteristics of the provider. This includes the entry points for its provider callback functions.
  • IfProviderContext
    A handle to a caller-provided context area for this network interface provider. Set this parameter to NULL if there is no context area.
  • pNdisProviderHandle
    A pointer to a caller-provided handle variable. If the registration operation succeeds, NDIS writes a handle to this variable that identifies the network interface provider. The interface provider should retain this handle for use in subsequent calls that require an interface provider handle.

Return Value

NdisIfRegisterProvider returns one of the following status values:

Value

Description

NDIS_STATUS_SUCCESS

The operation completed successfully.

NDIS_STATUS_RESOURCES

The operation failed because of insufficient resources.

NDIS_STATUS_INVALID_PARAMETER

NdisIfRegisterProvider failed to register the provider because the NDIS_IF_PROVIDER_CHARACTERISTICS structure at the ProviderCharacteristics parameter contained invalid member data.

NDIS_STATUS_NOT_SUPPORTED

NdisIfRegisterProvider failed to register the provider because the Header member in NDIS_IF_PROVIDER_CHARACTERISTICS specifies a structure version that is not supported.

Remarks

NDIS drivers call the NdisIfRegisterProvider function once during initialization to register as an NDIS interface provider. For example, the driver can call NdisIfRegisterProvider from its DriverEntry routine. An interface provider is a software component that manages network interfaces to support the MIB (RFC 2863).

To handle interface provider OID requests, interface providers provide entry points for callback functions in the NDIS_IF_PROVIDER_CHARACTERISTICS structure at the ProviderCharacteristics parameter of NdisIfRegisterProvider.

NDIS interface providers call the NdisIfRegisterInterface function to register a network interface. A provider can register multiple interfaces.

If NdisIfRegisterProvider succeeds, it returns a handle at the location that the pNdisProviderHandle parameter points to. The interface provider should retain this handle for use in subsequent calls that require an interface provider handle. For example, a driver must call NdisIfDeregisterProvider before the driver unloads.

A component that is no longer an interface provider can call the NdisIfDeregisterProvider function at any time to release the interface provider resources that NDIS allocated when the driver called NdisIfRegisterProvider.
