how do I pass this callback?

[Marc via Digitalmars-d-learn]

How do I define the callback so that it can be used in 
RegisterWaitForSingleObject()?

I've tried pass as argument:
myFunc
&myFunc
myFunc.ptr

none worked. Here's my code:

extern (C) void OnExited(void* context, BOOLEAN isTimeOut);

extern(Windows):
        BOOL RegisterWaitForSingleObject(
          PHANDLE             phNewWaitObject,
          HANDLE              hObject,
          WAITORTIMERCALLBACK Callback,
          PVOID               Context,
          ULONG               dwMilliseconds,
          ULONG               dwFlags
        );

Function call:

RegisterWaitForSingleObject(&hWait, hProcess, &OnExited, NULL, 
INFINITE, WT_EXECUTEONLYONCE);

Error:

void* hObject, extern (Windows) void function(void*, bool) 
Callback, void* Context, uint dwMilliseconds, uint dwFlags) is 
not callable using argument types (void**, void*, extern (C)
