# MPI_Get_version

Gets the version of MPI

## Synopsis

    #include "mpi.h"
    int MPI_Get_version(
     int *version,
     int *subversion )

## Output Parameters

| version | Major version of MPI (1 or 2)
| subversion | Minor version of MPI.

## Notes

The defined values `MPI_VERSION` and `MPI_SUBVERSION` contain the same information. This routine allows you to check that the library matches the version specified in the `mpi.h` and `mpif.h` files.

## Notes for Fortran

All MPI routines in Fortran (except for `MPI_WTIME` and `MPI_WTICK`) have an additional argument `ierr` at the end of the argument list. `ierr` is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the `call` statement.

All MPI objects (e.g., `MPI_Datatype`, `MPI_Comm`) are of type `INTEGER` in Fortran.
