Microsoft Specific
Provides the address of the memory ___location that holds the return address of the current function. This address may not be used to access other memory locations (for example, the function's arguments).

Header file <intrin.h>
Remarks
When _AddressOfReturnAddress is used in a program compiled with /clr, the function containing the _AddressOfReturnAddress call is compiled as a native function. When a function compiled as managed calls into the function containing _AddressOfReturnAddress, _AddressOfReturnAddress might not behave as expected.
This routine is only available as an intrinsic.
Example
// compiler_intrinsics_AddressOfReturnAddress.cpp
// processor: x86, x64
#include <stdio.h>
#include <intrin.h>
// This function will print three values:
// (1) The address retrieved from _AddressOfReturnAdress
// (2) The return address stored at the ___location returned in (1)
// (3) The return address retrieved the _ReturnAddress* intrinsic
// Note that (2) and (3) should be the same address.
