Is there any way to test for going out of scope in C?

Question

C++ / C#

Actually, my question is pretty exhaustive. Should be used for advanced logging of entering and exiting functions.

If you are not afraid of GCC extensions, then here: https://gcc.gnu.org/onlinedocs/gcc-4.0.4/gcc/Varia...

cleanup (cleanup_function)
The cleanup attribute runs a function when the variable goes out of scope. This attribute can only be applied to auto function scope variables; it may not be applied to parameters or variables with static storage duration. The function must take one parameter, a pointer to a type compatible with the variable. The return value of the function (if any) is ignored.
