| 45 | .SH DESCRIPTION |
---|
| 46 | .ft R |
---|
| 47 | Returns the error string associated with an error code or class. The argument string must represent storage that is at least MPI_MAX_ERROR_STRING characters long. |
---|
| 48 | .sp |
---|
| 49 | The number of characters actually written is returned in the output |
---|
| 50 | argument, resultlen. |
---|
| 51 | |
---|
| 52 | .SH ERRORS |
---|
| 53 | 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. |
---|
| 54 | .sp |
---|
| 55 | Before the error value is returned, the current MPI error handler is |
---|
| 56 | 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. |
