450     CHKERRQ(ierr) is fundamentally a macro replacement for

452 
453     Although typical usage resembles "void CHKERRQ(PetscErrorCode)" as described above, for certain uses it is
454     highly inappropriate to use it in this manner as it invokes return(PetscErrorCode). In particular,
455     it cannot be used in functions which return(void) or any other datatype.  In these types of functions,
456     you can use CHKERRV() which returns without an error code (bad idea since the error is ignored or
457          if (ierr) {PetscError(....); return(YourReturnType);}
458     where you may pass back a NULL to indicate an error. You can also call CHKERRABORT(comm,n) to have
459     MPI_Abort() returned immediately.
