418 
419     Although typical usage resembles "void CHKERRQ(PetscErrorCode)" as described above, for certain uses it is
420     highly inappropriate to use it in this manner as it invokes return(PetscErrorCode). In particular,
421     it cannot be used in functions which return(void) or any other datatype.  In these types of functions,
422     you can use CHKERRV() which returns without an error code (bad idea since the error is ignored or
