# MPI library
**MPI (Message Passing Interface)** is a library that enables you to write parallel programs in C or Fortran77. The library uses commonly available operating system services to create parallel processes and exchange information among these processes.

# MPI_Finalized

This function indicates if the `MPI_Finalize` method was called in a program.

# Syntax

```C
int MPI_Finalized(int *flag)
```

# Parameters

* **`flag`** acts as an output parameter that returns `true` if the `MPI_Finalize` is called, and returns `false` otherwise.

# Return value

The function returns an error if it is unsuccessful. By default, the error aborts the MPI job.

In case of success, it returns **`MPI_SUCCESS`**, the value returned upon successful termination of any MPI routine.
