[petsc-users] using PETSC_NULL_INTEGER in preallocation routines

[Klaij, Christiaan]

With petsc-3.7.5, I had F90 code like this:

  CALL MatSeqAIJSetPreallocation(aa_symmetric,PETSC_NULL_INTEGER,d_nnz,ierr); CHKERRQ(ierr)
  CALL MatMPIAIJSetPreallocation(aa_symmetric,PETSC_NULL_INTEGER,d_nnz,PETSC_NULL_INTEGER,o_nnz,ierr); CHKERRQ(ierr)

which worked fine. Now, with petsc-3.8.4, the same code gives this compilation error:

  error #6634: The shape matching rules of actual arguments and dummy arguments have been violated.   [PETSC_NULL_INTEGER]
  CALL MatSeqAIJSetPreallocation(aa_symmetric,PETSC_NULL_INTEGER,d_nnz,ierr); if (ierr .ne. 0) then ; call PetscErrorF(ierr); return; endif
----------------------------------------------^
  error #6634: The shape matching rules of actual arguments and dummy arguments have been violated.   [PETSC_NULL_INTEGER]
  CALL MatMPIAIJSetPreallocation(aa_symmetric,PETSC_NULL_INTEGER,d_nnz,PETSC_NULL_INTEGER,o_nnz,ierr); if (ierr .ne. 0) then ; call PetscErrorF(ierr); return; endif
----------------------------------------------^

What's the intended usage now, simply 0 instead of PETSC_NULL_INTEGER?
