  • Article

Called by the Windows Biometric Framework to give the Storage Adapter the chance to perform any initialization that remains incomplete.

HRESULT PibioStoragePipelineInitFn(
  [in, out] PWINBIO_PIPELINE Pipeline
)
{...}

Parameters

[in, out] Pipeline

Pointer to the WINBIO_PIPELINE structure associated with the biometric unit performing the operation.

Return value

If the function succeeds, it returns S_OK. If the function fails, it must return one of the following HRESULT values to indicate the error.

Return code Description
E_some_error
Any error code will cause the Biometric Service to log the error and abort the configuration of the biometric unit.

Remarks

The Storage Adapter should return S_OK if it doesn’t need to perform any initialization at this point.

When this routine is called, the SensorAdapterAttach, EngineAdapterAttach, and StorageAdapterAttach routines have completed normally.

This method executes in the context of an arbitrary RPC server thread.
