hello friends,

Suppose I have 2 functions, fun_A() and fun_B().

Now fun_B is calling fun_A. So In fun_B how can i know tht "fun_A" has called me ?

I wanna make a C prog for the same....

Pass the name of the caller as an argument.

Not so sure how much relevant this is, but looks interesting.

One method is to walk the call stack yet as how to do this is dependant on the system you are using. glibc gives you a backtrace, windows has StackWalk64, then there is __builtin_return_address and __builtin_frame_address.

edit:
What are you trying to achieve here is this for debugging information of say the allocation point or is this something completely different?

Pass the fun_b() as an argument the name of the calling function.
[ So it will now become - fun_b(String caller) ]
