MPI_Unpublish_name

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 applications 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++ 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.

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.
