### Input Parameters

### Notes

REQUIRES a call to PetscSynchronizedFlush() by all the processes after the completion of the calls to PetscSynchronizedPrintf() for the information from all the processors to be printed.

### Fortran Note

The call sequence is PetscSynchronizedPrintf(MPI_Comm, character(*), PetscErrorCode ierr) from Fortran. That is, you can only pass a single character string from Fortran.
