| 45 | .SH DESCRIPTION |
---|
| 46 | .ft R |
---|
| 47 | This routine associates an error string with an error code or |
---|
| 48 | class. Calling MPI_Add_error_string for an error code or class that |
---|
| 49 | already has an associated error string will replace the old string |
---|
| 50 | with the new one. It is erroneous to call MPI_Add_error_string for an |
---|
| 51 | error value not generated via MPI_Add_error_class or |
---|
| 52 | MPI_Add_error_code (e.g., an error code or class with a value not |
---|
| 53 | greater than MPI_LAST_ERRCODE). |
---|
| 54 | |
---|
| 55 | .SH ERRORS |
---|
| 56 | .ft R |
---|
| 57 | Almost all MPI routines return an error value; C routines as |
---|
| 58 | the value of the function and Fortran routines in the last argument. C++ |
---|
| 59 | functions do not return errors. If the default error handler is set to |
---|
| 60 | MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism |
---|
| 61 | will be used to throw an MPI:Exception object. |
---|
| 62 | .sp |
---|
| 63 | Before the error value is returned, the current MPI error handler is |
---|
| 64 | called. By default, this error handler aborts the MPI job, except for |
---|
| 65 | I/O function errors. The error handler may be changed with |
---|
| 66 | MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN |
---|
| 67 | may be used to cause error values to be returned. Note that MPI does not |
---|
| 68 | guarantee that an MPI program can continue past an error. |
