| 45 | .SH DESCRIPTION |
---|
| 46 | .ft R |
---|
| 47 | MPI_Comm_create_errhandler creates an error handler that can be attached to communicators. This function is identical to MPI_Errhandler_create, the use of which is deprecated. |
---|
| 48 | .sp |
---|
| 49 | In C, the user routine should be a function of type MPI_Comm_errhandler_fn, which is defined as |
---|
| 50 | .sp |
---|
| 51 | .nf |
---|
| 52 | typedef void MPI_Comm_errhandler_fn(MPI_Comm *, int *, \&...); |
---|
| 53 | .fi |
---|
| 54 | .sp |
---|
| 55 | The first argument is the communicator in use. The second is the error code |
---|
| 56 | to be returned by the MPI routine that raised the error. This typedef replaces MPI_Handler_function, the use of which is deprecated. |
---|
| 57 | .sp |
---|
| 58 | In Fortran, the user routine should be of this form: |
---|
| 59 | .sp |
---|
| 60 | .nf |
---|
| 61 | SUBROUTINE COMM_ERRHANDLER_FN(COMM, ERROR_CODE, \&...) |
---|
| 62 | INTEGER COMM, ERROR_CODE |
---|
| 63 | .fi |
---|
| 64 | .sp |
---|
| 65 | In C++, the user routine should be of this form: |
---|
| 66 | .sp |
---|
| 67 | .nf |
---|
| 68 | typedef void MPI::Comm::Errhandler_fn(MPI_Comm &, int *, \&...); |
---|
| 69 | .fi |
---|
| 70 | |
---|
| 71 | .SH ERRORS |
---|
| 72 | 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. |
---|
| 73 | .sp |
---|
| 74 | Before the error value is returned, the current MPI error handler is |
---|
| 75 | 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. |
