# Name

`MPI_Finalized`  - Checks whether MPI has been finalized

# Syntax

## C Syntax

```c
#include <mpi.h>

int MPI_Finalized(int *flag)
```

## Fortran Syntax

```fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_FINALIZED(FLAG, IERROR)
    LOGICAL	FLAG
    INTEGER	IERROR
```

## Fortran 2008 Syntax

```fortran
USE mpi_f08

MPI_Finalized(flag, ierror)
    LOGICAL, INTENT(OUT) :: flag
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror
```

# Output Parameter

* `flag` : True if MPI was finalized, and false otherwise (logical).
* `IERROR` : Fortran only: Error status (integer).

# Description

This routine may be used to determine whether MPI has been finalized. It
is one of a small number of routines that may be called before MPI is
initialized and after MPI has been finalized (`MPI_Initialized` is
another).

# Errors

Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with
`MPI_Comm_set_errhandler`; the predefined error handler `MPI_ERRORS_RETURN`
may be used to cause error values to be returned. Note that MPI does not
guarantee that an MPI program can continue past an error.
