MPE_Update - Updates an X11 display
int MPE_Update( handle )
handle - MPE graphics handle.
Only after an MPE_Update can you count on seeing the results of MPE
drawing routines. This is caused by the buffering of graphics requests
for improved performance.
NOTES FOR FORTRAN INTERFACE
The Fortran interface to this routine is different from its C
counterpart and it has an additional argument, ierr, at the end of the
argument list, i.e. the returned function value (the error code) in C
interface is returned as the additional argument in Fortran interface.
The Fortran interface is invoked with the CALL statement.
All MPI and MPE objects, MPI_Comm, MPE_XGraph and MPE_Color, are of
type INTEGER in Fortran.
