[petsc-dev] PetscContainerSetPointer

[Mark Adams]

I had some problems giving a container an PETSc object so I wrapped it in a
struct.
I forget what problem I had. Maybe ISColoringDestroy can't take a void*.
I'd like to check if I was just missing something.
Should something like this work?

    ISColoring c;
    ....
    ierr = PetscContainerSetPointer(container,(void*)c);CHKERRQ(ierr);
    ierr =
PetscContainerSetUserDestroy(container, ISColoringDestroy);CHKERRQ(ierr);
