_AddressOfReturnAddress

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).

void * _AddressOfReturnAddress();

Requirements

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.
__declspec(noinline)
void func() {
   void* pvAddressOfReturnAddress = _AddressOfReturnAddress();
   printf_s("%p\n", pvAddressOfReturnAddress);
   printf_s("%p\n", *((void**) pvAddressOfReturnAddress));
   printf_s("%p\n", _ReturnAddress());
}
 
int main() {
   func();
}
