270   PetscErrorCode. For example, PetscCall() may not be used in functions returning void, use
271   PetscCallVoid() in this case.

299     In the main program and in Fortran subroutines that do not have ierr as the final return parameter one

453 - ierr - nonzero error code, see the list of standard error codes in include/petscerror.h
454 
455   Notes:
456   This macro has identical type and usage semantics to PetscCall() with the important caveat
457   that this macro does not return. Instead, if ierr is nonzero it calls the PETSc error handler
458   and then immediately calls MPI_Abort(). It can therefore be used anywhere.
459 
460   As per MPI_Abort semantics the communicator passed must be valid, although there is currently
461   no attempt made at handling any potential errors from MPI_Abort(). Note that while
462   MPI_Abort() is required to terminate only those processes which reside on comm, it is often
463   the case that MPI_Abort() terminates *all* processes.

834 
835     Input Parameter:
836 .   format - the usual printf() format string
837 
838    Options Database Keys:
839 +    -error_output_stdout - cause error messages to be printed to stdout instead of the  (default) stderr
840 -    -error_output_none - to turn off all printing of error messages (does not change the way the error is handled.)
841 
842    Notes:
843     Use
844 $     PetscErrorPrintf = PetscErrorPrintfNone; to turn off all printing of error messages (does not change the way the
845 $                        error is handled.) and
846 $     PetscErrorPrintf = PetscErrorPrintfDefault; to turn it back on or you can use your own function
847 
848           Use
849      PETSC_STDERR = FILE* obtained from a file open etc. to have stderr printed to the file.
850      PETSC_STDOUT = FILE* obtained from a file open etc. to have stdout printed to the file.
851 
852           Use
853       PetscPushErrorHandler() to provide your own error handler that determines what kind of messages to print
