C++ Static Initialization Order: A New Solution to an Old Problem

//SafeB.cpp

#include "SafeA.h"
#include "SafeB.h"

//Pull in instance of CSafeA
extern Implement_pseudo_static( CSafeA ) s_SafeA;

//Safe Static instance initialisation
Implement_pseudo_static( CSafeB ) s_SafeB;

//CSafeB default constructor depends on s_SafeA
//This dependency could be much more complex and 
//difficult to determine in a real aplication
CSafeB::CSafeB()
{
	OutputDebugString( _T("SafeB has now been constructed\n" ) );
	s_SafeA->Squawk();	
}
