I'm not to familiar with the x86 architecture but for an ARM architecture you can just look at the link register, R14. This will give you the address of the function that called you. It is used to store where the code goes to upon 'return' and therefore will contain the address you want. I would be pretty sure that there is something similar in x86, have a look through the register definitions.
