MPI_Win_delete_attr(3) Open MPI MPI_Win_delete_attr(3)
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
C++ Syntax
#include <mpi.h>
void MPI::Win::Delete_attr(int win_keyval)
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. C++ func-
tions 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.
