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
