RedHat 9 (Linux i386) - man page for mpi_win_set_name (redhat section 3)

MPI_Win_set_name(3)			     LAM/MPI			      MPI_Win_set_name(3)

NAME
       MPI_Win_set_name -  Set a name on a window

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

INPUT PARAMETERS
       win    - MPI window
       name   - Pointer to the name of window

NOTES
       This function associates a name with a window, which can be useful for debugging purposes.
       The function MPI_Win_get_name can be used to retrieve name that was  previously	set  with
       MPI_Win_set_name
	.

       Names  passed  in  C  must  include  the  null  terminator,  and  can be of maximum length
       MPI_MAX_OBJECT_NAME (including the null terminator).  Names passed  in  Fortran	can  also
       have a maximum length of MPI_MAX_OBJECT_NAME
	.

       Setting	a  name  on  a window that already has a name associated with it replaces the old
       name.

ERRORS
       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.
       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
       MPI_ERR_WIN
	      - Invalid window.  A common error is to use a null window in a call.
       MPI_ERR_ARG
	      -  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.

MORE INFORMATION
       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).
