NAME
MPI_Unpublish_name - Unpublishes a service name
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Unpublish_name(char *service_name, MPI_Info info,
char *port_name)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_UNPUBLISH_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR)
CHARACTER*(*) SERVICE_NAME, PORT_NAME
INTEGER INFO, IERROR
C++ Syntax
#include <mpi.h>
void MPI::Unpublish_name(const char* service_name, const MPI::Info& info,
char* port_name)
INPUT PARAMETERS
service_name A service name (string).
info Options to the name service functions (handle). No
options currently supported.
port_name A port name (string).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine removes the pair (service_name, port_name) so that appli-
cations may no longer retrieve port_name by calling MPI_Lookup_name. It
is an error to unpublish a service_name that was not published via
MPI_Publish_name. Both the service_name and port_name arguments to
MPI_Unpublish_name must be identical to the arguments to the previous
call to MPI_Publish_name.
The info parameter should be MPI_INFO_NULL, as this routine does not
parse any MPI Info arguments.
ERRORS
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument. C++ func-
tions 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.
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for
