pointer to PE macro defined

Hi:

I have this macro in my project:

#define Col1_GetVal() ( \
(bool)((getReg8(PTAD) & 0x10)) /* Return port data */ \
)

I have severals Colx_GetVal macros and i need use a array of pointers to them:

ptr[0]= &Col1_GetVal;

ptr[1]= &Col2_GetVal;

and so....

Anybody can give me some tip how i can o it?

Best Regards.

Mauricio.

macros don't have address, thus pointers can't point to macros.

But you may convert macros into functions like this

bool Col1_GetVal(void)

{

(bool)((getReg8(PTAD) & 0x10)) /* Return port data */ \
}

Define array of pointers :

char (*array[3])(void);

array[2] = &foo; // assign

array[2](); // call foo

To call PE macros proceed like above, but define your own functions and make them calling PE macros.
