36 | .SH DESCRIPTION |
---|
37 | This deprecated routine is not available in C++. |
---|
38 | .sp |
---|
39 | Note that use of this routine is \fIdeprecated\fP as of MPI-2. Please use MPI_Comm_delete_attr. |
---|
40 | .sp |
---|
41 | Delete attribute from cache by key. This function invokes the attribute delete function delete_fn specified when the keyval was created. The call will fail if the delete_fn function returns an error code other than MPI_SUCCESS. |
---|
42 | |
---|
43 | Whenever a communicator is replicated using the function MPI_Comm_dup, all callback copy functions for attributes that are currently set are invoked (in arbitrary order). Whenever a communicator is deleted using the function MPI_Comm_free, all callback delete functions for attributes that are currently set are invoked. |
---|

---|
45 | .SH ERRORS |
---|
46 | 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. |
---|
47 | .sp |
---|
48 | Before the error value is returned, the current MPI error handler is |
---|
49 | called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler |
---|
50 | 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. |
