- AsyncResult [in]
Pointer to a WINBIO_ASYNC_RESULT structure that contains information about the completed operation. The structure is created by the Windows Biometric Framework. You must call WinBioFree to release the structure.
Do not return a value from your implementation of this function.
You must create this callback if you open a biometric session by using the WinBioAsyncOpenSession function or the WinBioAsyncOpenFramework function and you set WINBIO_ASYNC_NOTIFY_CALLBACK in the NotificationMethod parameter of either function.
