[petsc-users] recommended error-checking for PetscInitialize() and PetscFinalize()

[Ed Bueler]

Dear PETSc --

I notice in the users manual that the C examples show

ierr = PetscInitialize(&argc,&args,(char*)0,help);if (ierr) return ierr;

at the start of main() and

ierr = PetscFinalize();
return ierr;

at the end of main().  Is this the deliberate, recommended style?  My
understanding of these choices is that if PetscInitialize() fails then
CHKERRQ(ierr) may not do the right thing, while if PetscFinalize() fails
then that should be the result of main() (without any fiddling by CHKERRQ
etc.).  Is this the correct understanding?

Thanks,

Ed
