10 int
11 MPI_Win_get_name(MPI_Win win, char *name, int *length)
12
14 type - MPI window
15
16
18 name - Name of the window
19 length - Integer length of the resulting name

23 This function returns the name of a window that was previously set with
24 MPI_Win_set_name . If a name was not previously associated with a win‐
25 dow, the returned string will be empty and length will be 0. The
26 retuned name will be a maximum of MPI_MAX_OBJECT_NAME characters long.

30 If an error occurs in an MPI function, the current MPI error handler is
31 called to handle it. By default, this error handler aborts the MPI
32 job. The error handler may be changed with MPI_Errhandler_set ; the
33 predefined error handler MPI_ERRORS_RETURN may be used to cause error
34 values to be returned (in C and Fortran; this error handler is less
35 useful in with the C++ MPI bindings. The predefined error handler
36 MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value
37 needs to be recovered). Note that MPI does not guarantee that an MPI
38 program can continue past an error.
39
40 All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error
41 value; C routines as the value of the function and Fortran routines in
42 the last argument. The C++ bindings for MPI do not return error val‐
43 ues; instead, error values are communicated by throwing exceptions of
44 type MPI::Exception (but not by default). Exceptions are only thrown
45 if the error value is not MPI::SUCCESS .
46
47
48 Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI
49 functions will return upon an error, there will be no way to recover
50 what the actual error value was.
51 MPI_SUCCESS
52 - No error; MPI routine completed successfully.
53 MPI_ERR_COMM
54 - Invalid communicator. A common error is to use a null commu‐
55 nicator in a call (not even allowed in MPI_Comm_rank ).
56 MPI_ERR_ARG
57 - Invalid argument. Some argument is invalid and is not identi‐
58 fied by a specific error class. This is typically a NULL
59 pointer or other such error.

69 contains the text of both the MPI-1 and MPI-2 standards. These docu‐
70 ments contain detailed information about each MPI function (most of
71 which is not duplicated in these man pages).
