+Routine Description:
+
+ Determines the handles that are currently active in the database.
+ It's the caller's responsibility to free handle buffer.
+
+Arguments:
+
+ This - A pointer to the EFI_HII_PROTOCOL instance.
+ HandleBufferLength - On input, a pointer to the length of the handle buffer. On output,
+ the length of the handle buffer that is required for the handles found.
+ HiiHandleBuffer - Pointer to an array of EFI_HII_PROTOCOL instances returned.
+
+Returns:
+
+ EFI_SUCCESS - Get an array of EFI_HII_PROTOCOL instances successfully.
+ EFI_INVALID_PARAMETER - Hii is NULL.
+ EFI_NOT_FOUND - Database not found.
