# PetscSynchronizedPrintf
Prints synchronized output from multiple MPI processes. Output of the first processor is followed by that of the second, etc. 
## Synopsis
```
PetscErrorCode PetscSynchronizedPrintf(MPI_Comm comm, const char format[], ...)
```
Not Collective


## Input Parameters

- ***comm -*** the MPI communicator
- ***format -*** the usual `printf()` format string





## Note
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).
That is, you can only pass a single character string from Fortran.


## See Also
