The PetscObjectState* and PetscObjectComposedData* routines are in petscimpl, but documented as a public API. It would be nice to turn all these macros into functions (which will change their signature). I'm dubious of any claims that these are called in a context where a static function call would be a performance limitation. On Tue, Feb 12, 2013 at 9:39 AM, Jed Brown <[email protected]> wrote:

petscsys.h no longer includes petscimpl.h (including the _p_PetscObject definition) and petscvec.h no longer includes vecimpl.h (including _p_Vec). Users that need direct access can include the private headers, but we encourage you to explain your use case here so that we can provide a suitable public API.
