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
