How to get the length of a function in bytes?

Question

I want to know the length of C function (written by me) at runtime. Any method to get it? It seems sizeof doesn\'t work here.

Answer 1

In e.g. Codewarrior, you can place labels around a function, e.g.

label1:
void someFunc()
{
    /* code goes here. */
}
label2:

and then calculate the size like (int)(label2-label1), but this is obviously very compiler dependent. Depending on your system and compiler, you may have to hack linker scripts, etc.
