MPI_Win_get_name - Obtains the name of a window.

17.2.448.1. SYNTAX

17.2.448.1.1. C Syntax

#include <mpi.h>

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

17.2.448.1.2. 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

17.2.448.1.3. 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

17.2.448.2. INPUT PARAMETER

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

17.2.448.3. 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).

17.2.448.4. DESCRIPTION

17.2.448.5. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
