I already answered this one in another thread where you asked about
it.

The offset of a function is just its address cast to an unsigned
long.  Here's how to compute an offset of a hypothetical function
my_func:

    unsigned long func_offset = (unsigned long)my_func;

The offset of a variable is its address cast to an unsigned long:

    unsigned long var_offset = (unsigned long)&my_var;
