43 | .SH DESCRIPTION |
---|
44 | .ft R |
---|
45 | MPI_Win_create_errhandler should be, in C, a function of type MPI_Win_errhandler_fn, which is defined as |
---|
46 | .sp |
---|
47 | .nf |
---|
48 | typedef void MPI_Win_errhandler_fn(MPI Win *, int *, ...); |
---|
49 | .fi |
---|
50 | .sp |
---|
51 | The first argument is the window in use, the second is the error code to be returned. |
---|
52 | .sp |
---|
53 | In Fortran, the user routine should be of the form: |
---|
54 | .sp |
---|
55 | .nf |
---|
56 | SUBROUTINE WIN_ERRHANDLER_FN(WIN, ERROR_CODE, ...) |
---|
57 | INTEGER WIN, ERROR_CODE |
---|
58 | .fi |
---|
59 | .sp |
---|
60 | In C++, the user routine should be of the form: |
---|
61 | .sp |
---|
62 | .nf |
---|
63 | typedef void MPI::Win::Errhandler_fn(MPI::Win &, int *, ...); |
---|
64 | .fi |
---|
65 | |
---|
66 | .SH ERRORS |
---|
67 | 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. |
---|
68 | .sp |
---|
69 | Before the error value is returned, the current MPI error handler is |
---|
70 | 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. |
