[petsc-users] How to use PetscViewerVTKGetDM

[陳宗興]

Hi,

I have created a DMPlex using DMPlexCreateFromFile,
and I use PetscObjectSetName to create the name of DM.
I have occurred some problem when I try to use PetscViewerVTKGetDM.
This is what I write:

     DM   dm;
     ...
     PetscObjectSetName((PetscObject) dm, "Mesh");
     ...
     PetscViewerVTKGetDM(viewer, (PetscObject) dm);

And here is the output of waring:
     warning: passing argument 2 of ‘PetscViewerVTKGetDM’ from incompatible
pointer type [-Wincompatible-pointer-types]
     ierr = PetscViewerVTKGetDM(viewer, (PetscObject) dm);CHKERRQ(ierr);
                                                                  ^
     note: expected ‘struct _p_PetscObject **’ but argument is of type
‘struct _p_PetscObject *'
     PETSC_EXTERN PetscErrorCode
PetscViewerVTKGetDM(PetscViewer,PetscObject*);

 ^~~~~~~~~~~~~~~~~~~

How can I fix it?

Thank you,

Barry
