### Input Parameters

| comm | - the communicator
| format | - the usual printf() format string

### Notes

REQUIRES a intervening call to PetscSynchronizedFlush() 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.
