Converting LPTHREAD_START_ROUTINE to int

I'm working with a C++ code base which contains some lines 开发者_JAVA百科like the following:

CreateThread(NULL, 0, MyThreadMethod, NULL, 0, NULL); 

I would like to write the value of MyThreadMethod to debug output. (I suppose it's a hexadecimal address). MyThreadMethod has the type LPTHREAD_START_ROUTINE. I already have a method called OutputDebugInt which can write an int to debug output. When I to compile the line

OutputDebugInt(MyThreadMethod);

then the compiler issues the error

cannot convert parameter 1 from unsigned long (__stdcall *)(void *) to int.

So is there a way to convert LPTHREAD_START_ROUTINE to int (or something else which can be written to debug output)?

std::basic_ostringstream<TCHAR> ss;
ss << static_cast<void*>(&MyThreadMethod);
::OutputDebugString(ss.str().c_str());

Converting to int is possible on 32-bit platforms, but not 64-bit platforms, so I'd stick with creating a string instead.
