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).
Syntax
void * _AddressOfReturnAddress();
Requirements
Intrinsic | Architecture |

_AddressOfReturnAddress |
x86, x64 |
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.
