Name

MPI_Win_delete_attr - 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.

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.
