MPI_Get_version(3)                 Open MPI                 MPI_Get_version(3)



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++
       functions 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.
