SYNTAXC 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
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.
See the MPI man page for a full list of MPI error codes.
