422 .  ierr - nonzero error code, see the list of standard error codes in include/petscerror.h

424   Level: beginner
425 
426    Notes:
427     Once the error handler is called the calling function is then returned from with the given error code.
428 
429     Experienced users can set the error handler with PetscPushErrorHandler().
430 
431     CHKERRQ(ierr) is fundamentally a macro replacement for
432          if (ierr) return(PetscError(...,ierr,...));
433 
434     Although typical usage resembles "void CHKERRQ(PetscErrorCode)" as described above, for certain uses it is
435     highly inappropriate to use it in this manner as it invokes return(PetscErrorCode). In particular,
436     it cannot be used in functions which return(void) or any other datatype.  In these types of functions,
437     you can use CHKERRV() which returns without an error code (bad idea since the error is ignored or
438          if (ierr) {PetscError(....); return(YourReturnType);}
439     where you may pass back a NULL to indicate an error. You can also call CHKERRABORT(comm,n) to have
440     MPI_Abort() returned immediately.
