 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
