NAME

       MPI_Win_get_name -  Get the print name associated with the MPI RMA window

SYNOPSIS

       int MPI_Win_get_name(MPI_Win win, char *win_name, int *resultlen)

INPUT PARAMETERS

       win    - window whose name is to be returned (handle)

OUTPUT PARAMETERS

       win_name
              - the name previously stored on the window, or a empty string if no such name exists (string)
       resultlen
              - length of returned name (integer)

THREAD AND INTERRUPT SAFETY

       This  routine  is  thread  and  interrupt  safe only if no MPI routine that updates or frees the same MPI
       object may be called concurrently with this routine.

       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.
       MPI_ERR_WIN
              - Invalid MPI window object
       MPI_ERR_OTHER
              - Other error; use MPI_Error_string to get more information about this error code.
       MPI_ERR_ARG
              - Invalid argument.  Some argument is invalid and is not identified  by  a  specific  error  class
              (e.g., MPI_ERR_RANK ).
