I think you want:

   using Teuchos::outArg; Teuchos::inOutArg;
   ...
   Thyra::uninitializePrec<double>(precFactory, inoutArg(prec), outArg(fwdOpSrc), outArg(supportSolveUse)); 

I would have to see more context to see your types for 'precFactory', 'prec', 'fwdOpSrc' and 'supportSolveUse' to know for sure.

The above helper function Thyra::uninitializePrec<>(...) is defined in the header Thyra_PreconditionerFactoryHelpers.hpp

Let me know if this does not work for you,

P.S. We are not quite fully finished refactoring Thyra to remove raw C++ pointers using the convention defined in http://www.cs.sandia.gov/~rabartl/TeuchosMemoryManagementSAND.pdf .  That is part of the confusion.  In general, the non-member helpers are updated before the virtual member functions due to backward comparability challenges.
