Yes and no. You can enumerate the access list and find the
function pointer symbol. You can also find the instruction that
call to the function pointer.

However, that does not tell you want value is in that function
pointer. You need to do date flow analyze to find out the
value in the function pointer. In other words, exactly which function
it is call to. If the pointer is load from memory, it is very hard
to trace. That pointer value can be overwritten by any code.
