[petsc-users] PetscViewerFileSetName() wrong error code in Fortran

[Tim Steinhoff]

Dear PETSc Team,

I am having the issue that petscviewerfilesetname_() and
petscviewerfilegetname_() in
src\sys\classes\viewer\impls\ascii\ftn-custom\zfilevf.c (Fortran) do
not return proprer error codes, as those are not checked immediately
after the actual call and will be overwritten afterwards within the
macro FREECHAR() or by other subsequent calls respectively.

It would be very helpful if you could fix that.

Thanks and king regards,

Volker
