MPI_Get_version(3OpenMPI)												 MPI_Get_version(3OpenMPI)

NAME
       MPI_Get_version - Returns the version of the standard corresponding to the current implementation.

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Get_version(int *version, int *subversion)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_GET_VERSION(VERSION, SUBVERSION, IERROR)
	    INTEGER   VERSION, SUBVERSION, IERROR

C++ Syntax
       #include <mpi.h>
       void Get_version(int& version, int& subversion)

OUTPUT PARAMETERS
       version	 The major version number of the corresponding standard (integer).

       subversion
		 The minor version number of the corresponding standard (integer).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       Since Open MPI is MPI 2.0 compliant, this function will return a version value of 2 and a subversion value of 0 for this release.

NOTE
       MPI_Get_version is one of the few functions that can be called before MPI_Init and after MPI_Finalize.

ERRORS
       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception  mechanism
       will be used to throw an MPI:Exception object.

       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.
