.SH DESCRIPTION
|
|
.ft R
|
|
This routine removes the pair (\fIservice_name, port_name\fP) so that
|
|
applications may no longer retrieve \fIport_name\fP by calling
|
|
MPI_Lookup_name. It is an error to unpublish a \fIservice_name\fP
|
|
that was not published via MPI_Publish_name. Both the \fIservice_name\fP
|
|
and \fIport_name\fP arguments to MPI_Unpublish_name must be identical
|
|
to the arguments to the previous call to MPI_Publish_name.
|
|
.sp
|
|
The \fIinfo\fP parameter should be MPI_INFO_NULL, as this routine does
|
|
not parse any MPI Info arguments.
|
|
|
|
.SH ERRORS
|
|
.ft R
|
|
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.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
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.
|
|
.sp
|
|
See the MPI man page for a full list of MPI error codes.
