void MPI::Publish_name(const char* \fIservice_name\fP, const MPI::Info& \fIinfo\fP,
	const char* \fIport_name\fP)

.SH INPUT PARAMETERS
.ft R
.TP 1.4i
service_name
A service name (string).
.TP 1.4i
info
Implementation-specific information (handle).
.ft R
.TP 1.4i
port_name
A port name (string).

.SH OUTPUT PARAMETER
.TP 1.4i
IERROR
Fortran only: Error status (integer).

.SH DESCRIPTION
.ft R
This routine publishes the pair (\fIservice_name, port_name\fP) so that
an application may retrieve \fIport_name\fP by calling MPI_Lookup_name
with \fIservice_name\fP as an argument. It is an error to publish the same
\fIservice_name\fP twice, or to use a \fIport_name\fP argument that was
not previously opened by the calling process via a call to MPI_Open_port.
.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.
