MPI_Win_delete_attr

:ref:`MPI_Win_delete_attr` |mdash| Deletes an attribute from a window.

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Win_delete_attr(MPI_Win win, int win_keyval)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_WIN_DELETE_ATTR(WIN, WIN_KEYVAL, IERROR)
     INTEGER WIN, WIN_KEYVAL, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Win_delete_attr(win, win_keyval, ierror)
     TYPE(MPI_Win), INTENT(IN) :: win
     INTEGER, INTENT(IN) :: win_keyval
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT/OUTPUT PARAMETER

  • win: Window from which the attribute is deleted (handle).

INPUT PARAMETER

  • win_keyval: Key value (integer).

OUTPUT PARAMETER

  • ierror: Fortran only: Error status (integer).

NOTES

Note that it is not defined by the MPI standard what happens if the delete_fn callback invokes other MPI functions. In Open MPI, it is not valid for delete_fn callbacks (or any of their children) to add or delete attributes on the same object on which the delete_fn callback is being invoked.
