20 All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have
21 an additional argument ierr at the end of the argument list. ierr is
22 an integer and has the same meaning as the return value of the routine
23 in C. In Fortran, MPI routines are subroutines, and are invoked with
24 the call statement.
25
26 All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
27 Fortran.

31 The IMPI standard only supports MPI-1 functions. Hence, this function
32 is currently not designed to operate within an IMPI job.
33
34
36 If an error occurs in an MPI function, the current MPI error handler is
37 called to handle it. By default, this error handler aborts the MPI
38 job. The error handler may be changed with MPI_Errhandler_set ; the
39 predefined error handler MPI_ERRORS_RETURN may be used to cause error
40 values to be returned (in C and Fortran; this error handler is less
41 useful in with the C++ MPI bindings. The predefined error handler
42 MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value
43 needs to be recovered). Note that MPI does not guarantee that an MPI
44 program can continue past an error.
45
46 All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error
47 value; C routines as the value of the function and Fortran routines in
48 the last argument. The C++ bindings for MPI do not return error val‐
49 ues; instead, error values are communicated by throwing exceptions of
50 type MPI::Exception (but not by default). Exceptions are only thrown
51 if the error value is not MPI::SUCCESS .
52
53
54 Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI
55 functions will return upon an error, there will be no way to recover
56 what the actual error value was.
57 MPI_ERR_OTHER
58 - Other error; use MPI_Error_string to get more information
59 about this error code.
60 MPI_ERR_INTERN
61 - An internal error has been detected. This is fatal. Please
62 send a bug report to the LAM mailing list (see http://www.lam-
63 mpi.org/contact.php ).

72 For more information, please see the official MPI Forum web site, which
73 contains the text of both the MPI-1 and MPI-2 standards. These docu‐
74 ments contain detailed information about each MPI function (most of
75 which is not duplicated in these man pages).
