PetscErrorPrintf#

Prints error messages.

Synopsis#

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

Not Collective; No Fortran Support

Input Parameter#

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
