# 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.
