    CHKERRQ(ierr) is fundamentally a macro replacement for

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

/*MC
    PetscErrorPrintf - Prints error messages.

   Synopsis:
    #include <petscsys.h>
     PetscErrorCode (*PetscErrorPrintf)(const char format[],...);

    Not Collective

    Input Parameters:
.   format - the usual printf() format string

   Options Database Keys:
+    -error_output_stdout - cause error messages to be printed to stdout instead of the  (default) stderr
-    -error_output_none - to turn off all printing of error messages (does not change the way the error is handled.)

   Notes:
    Use
$     PetscErrorPrintf = PetscErrorPrintfNone; to turn off all printing of error messages (does not change the way the
$                        error is handled.) and
$     PetscErrorPrintf = PetscErrorPrintfDefault; to turn it back on or you can use your own function

          Use
     PETSC_STDERR = FILE* obtained from a file open etc. to have stderr printed to the file.
     PETSC_STDOUT = FILE* obtained from a file open etc. to have stdout printed to the file.

          Use
      PetscPushErrorHandler() to provide your own error handler that determines what kind of messages to print

    This routine is not supported in Fortran.
