NAME
MPI_Win_free_keyval - Frees a window keyval.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Win_free_keyval(int *win_keyval)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_WIN_FREE_KEYVAL(WIN_KEYVAL, IERROR)
INTEGER WIN_KEYVAL, IERROR
C++ Syntax
#include <mpi.h>
static void MPI::Win::Free_keyval(int& win_keyval)
INPUT/OUTPUT PARAMETER
win_keyval
Key value (integer).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
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.
