MPI_Win_get_name(3)			     LAM/MPI			      MPI_Win_get_name(3)

       MPI_Win_get_name -  Get the name associated with a window

       #include <mpi.h>
       MPI_Win_get_name(MPI_Win win, char *name, int *length)

       type   - MPI window

       name   - Name of the window
       length - Integer length of the resulting name

       This function returns the name of a window that was previously set with MPI_Win_set_name
	.   If	a  name  was not previously associated with a window, the returned string will be
       empty and length will be 0.  The retuned name will be  a  maximum  of  MPI_MAX_OBJECT_NAME
       characters long.

       If  an  error occurs in an MPI function, the current MPI error handler is called to handle
       it.  By default, this error handler aborts the MPI job.	The error handler may be  changed
       with  MPI_Errhandler_set  ;  the predefined error handler MPI_ERRORS_RETURN may be used to
       cause error values to be returned (in C and Fortran; this error handler is less useful  in
       with  the  C++  MPI  bindings.	The predefined error handler MPI::ERRORS_THROW_EXCEPTIONS
       should be used in C++ if the error value needs to be recovered).  Note that MPI	does  not
       guarantee that an MPI program can continue past an error.

       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.  The C++ bindings for
       MPI  do not return error values; instead, error values are communicated by throwing excep-
       tions of type MPI::Exception (but not by default).  Exceptions  are  only  thrown  if  the
       error value is not MPI::SUCCESS

       Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return
       upon an error, there will be no way to recover what the actual error value was.
	      - No error; MPI routine completed successfully.
	      - Invalid communicator.  A common error is to use a null	communicator  in  a  call
	      (not even allowed in MPI_Comm_rank ).
	      -  Invalid  argument.  Some argument is invalid and is not identified by a specific
	      error class.  This is typically a NULL pointer or other such error.

       For  more information, please see the official MPI Forum web site, which contains the text
       of both the MPI-1 and MPI-2 standards.  These documents contain detailed information about
       each MPI function (most of which is not duplicated in these man pages).
