17.2.443. MPI_Win_free_keyval

MPI_Win_free_keyval - Frees a window keyval.

17.2.443.1. SYNTAX

17.2.443.1.1. C Syntax

#include <mpi.h>

int MPI_Win_free_keyval(int *win_keyval)

17.2.443.1.2. Fortran Syntax

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

17.2.443.1.3. Fortran 2008 Syntax

USE mpi_f08
MPI_Win_free_keyval(win_keyval, ierror)
     INTEGER, INTENT(INOUT) :: win_keyval
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

17.2.443.2. INPUT/OUTPUT PARAMETER

  • win_keyval: Key value (integer).

17.2.443.3. OUTPUT PARAMETER

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

17.2.443.4. 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.
