USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_WIN_FREE_KEYVAL(WIN_KEYVAL, IERROR) INTEGER WIN_KEYVAL, IERROR
USE mpi_f08 MPI_Win_free_keyval(win_keyval, ierror) INTEGER, INTENT(INOUT) :: win_keyval INTEGER, OPTIONAL, INTENT(OUT) :: ierror
#include <mpi.h> static void MPI::Win::Free_keyval(int& win_keyval)
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions 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.
