NAME
MPI_Win_get_name - Obtains the name of a window.

SYNTAX

C Syntax
#include <mpi.h>
int MPI_Win_get_name(MPI_Win win, char *win_name, int *resultlen)

Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_GET_NAME(WIN, WIN_NAME, RESULTLEN, IERROR)
	INTEGER WIN, RESULTLEN, IERROR
	CHARACTER*(*) WIN_NAME

Fortran 2008 Syntax
USE mpi_f08
MPI_Win_get_name(win, win_name, resultlen, ierror)
	TYPE(MPI_Win), INTENT(IN) :: win
	CHARACTER(LEN=MPI_MAX_OBJECT_NAME), INTENT(OUT) :: win_name
	INTEGER, INTENT(OUT) :: resultlen
	INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT PARAMETER

win Window whose name is to be returned (handle).

OUTPUT PARAMETERS

win_name
    the name previously stored on the window, or an empty string if no such name exists (string).

resultlen
    Length of returned name (integer).

IERROR
    Fortran only: Error status (integer).

DESCRIPTION

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.
