Re: [avr-gcc-list] Dumb C question

You probably already know this, but anyway.....

One easy way is :

enum eMenuItem
{
     D_this,
     D_that,
     D_TheOtherThing,
     D_Last_Enum
}

The size is then simply D_Last_Enum

But as enum's can have init values like :

enum eMenuItem
{
     D_this = 50,
     D_that,
     D_TheOtherThing = 60,
     D_Last_Enum
}

D_Last_Enum would be wrong, so it's not foolproof.

As far as I know, there's no way to do it with sizeof ( ) .
