Re: Some issues with array of pointers to functions

The issues is when they are in the table they are considered data, not
function pointers, by C's abstract machine.

From my source code when I ran into the issue.  The nasty double cast
is needed to make the warning go away.:

              /*
               * You may not even convert a void * to a function
               * pointer by explicit casting (6.3.2.3|1).
               *
               * C's abstract machine does not assume that code and
               * data are addressed the same way, so as far as C is
               * concerned function pointers and data pointers have
               * nothing to do with each other (they could have
               * different widths).
               */

static uint8_t (*state_function_ptr)( uint8_t ); /* Pointer to
function to execute when selected from the menu */

              state_function_ptr = (uint8_t (*)(uint8_t))
PGM_READ_WORD( menu_state[current_state_u8].FunctionPointer );

              if( NULL != state_function_ptr )
                {
                  next_state_u8 = state_function_ptr( STATE_CHANGE );
/* Execute Function. It will return its current state to stay in this
state, or a new state for next time */
                 }
