NAME

       MPI_Close_port -  close port

SYNOPSIS

       int MPI_Close_port(const char *port_name)

INPUT PARAMETERS

       port_name
              - a port name (string)

THREAD AND INTERRUPT SAFETY

       The  user  is responsible for ensuring that multiple threads do not try to update the same
       MPI object from different threads.  This routine should not be used from within  a  signal
       handler.

       The  MPI standard defined a thread-safe interface but this does not mean that all routines
       may be called without any thread locks.  For example, two  threads  must  not  attempt  to
       change  the contents of the same MPI_Info object concurrently.  The user is responsible in
       this case for using some mechanism, such as thread locks, to ensure that only  one  thread
       at a time makes use of this routine.

NOTES FOR FORTRAN

       All  MPI  routines  in  Fortran  (except  for MPI_WTIME and MPI_WTICK ) have an additional
       argument ierr at the end of the argument list.  ierr  is  an  integer  and  has  the  same
       meaning  as  the  return  value  of  the  routine  in  C.   In  Fortran,  MPI routines are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value;  C  routines  as
       the  value of the function and Fortran routines in the last argument.  Before the value is
       returned, the current MPI error handler is called.  By default, this error handler  aborts
       the  MPI  job.   The  error  handler  may  be  changed  with  MPI_Comm_set_errhandler (for
       communicators), MPI_File_set_errhandler (for files), and MPI_Win_set_errhandler  (for  RMA
       windows).   The  MPI-1  routine  MPI_Errhandler_set may be used but its use is deprecated.
       The predefined error handler MPI_ERRORS_RETURN may be used to cause  error  values  to  be
       returned.   Note  that  MPI  does  not  guarentee that an MPI program can continue past an
       error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
