| 44 | .SH DESCRIPTION |
---|
| 45 | .ft R |
---|
| 46 | Registers the user routine \fIfunction\fP for use as an MPI exception handler. Returns in errhandler a handle to the registered exception handler. |
---|
| 47 | .sp |
---|
| 48 | In the C language, the user routine \fIfunction\fP should be a C function of type MPI_File_errhandler_fn, which is defined as |
---|
| 49 | .sp |
---|
| 50 | .nf |
---|
| 51 | typedef void (MPI_File_errhandler_fn)(MPI_File *, int *, |
---|
| 52 | \&...); |
---|
| 53 | .fi |
---|
| 54 | .sp |
---|
| 55 | The first argument to \fIfunction\fP is the file in use. The second is the error code |
---|
| 56 | to be returned by the MPI routine that raised the error. |
---|
| 57 | .sp |
---|
| 58 | In the Fortran language, the user routine should be of the form: |
---|
| 59 | .sp |
---|
| 60 | .nf |
---|
| 61 | SUBROUTINE FILE_ERRHANDLER_FN(FILE, ERROR_CODE, ...) |
---|
| 62 | INTEGER FILE, ERROR_CODE |
---|
| 63 | .fi |
---|
| 64 | .sp |
---|
| 65 | In C++, the user routine \fIfunction\fP should be of the form: |
---|
| 66 | .sp |
---|
| 67 | .nf |
---|
| 68 | typedef void MPI::File::Errhandler_fn(MPI::File &, int *, |
---|
| 69 | ...); |
---|
| 70 | .fi |
---|
| 71 | .sp |
---|
| 72 | |
---|
| 73 | .SH ERRORS |
---|
| 74 | 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. |
---|
| 75 | .sp |
---|
| 76 | Before the error value is returned, the current MPI error handler is |
---|
| 77 | called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error. |
