SizeOfArray() issue

[Tamamo]

I tried doing this:

int var = 1;
if(SizeOfArray(var)==-1)
    Link->Item[I_SWORD1]; 

Worked just find, except that it traced an error message in allegro.log saying that it tried to pass the value of var as an index into the array; returns -1 regardless of what number you put in as it should since it's not an array.

There's no way to make it work. If you modify your code as follows:

int arr[5];
int var = 1;
if(SizeOfArray(var)==-1)
    Link->Item[I_SWORD1];

you'll find that SizeOfArray(var) is 5, because arr==var (assuming there weren't any other arrays already). An array pointer is just a number, so an arbitrary number may well be a valid array pointer. There isn't a way we could distinguish between arrays and numbers without fundamental changes to the language.
