I have a few functions and their function pointers. I have to display the memory size of those functions. The problem is that if I use sizeof operator on the function pointers they return a constant value. so how then can I get the exact size of a function.
Most compilers and linkers put funtions into the object file in the order in which they appear in the code. Therefore you can put a dummy function after the function the size of which you want to know, than simply substract the adresses.
isnt there another proper way?
If there is, Jeffrey Richter doesn't know about it. My advise was from his book.
Remember that function pointers are just that--pointers. Therefore, they are expected to have the same size as any other pointer in the program (4 or 8 bytes).
