struct structSeperate { unsigned char uaHigh; unsigned char uaLow; }; union OneIntorTwoBytes { unsigned int un; struct structSeperate ua; }; void AFunction() { OneIntorTwoBytes unionMy; ... ...unionMy...// ... } In the above example, Could you please explain how many bytes of free mem will be allocated for AFunction()? How many bytes of free mem will be allocated for the whole module?
The unionMy variable (which is a union) will take 2 bytes. I don't know how much space is used by your function. Jon
