[Boost-users] [thread] call_once question

12 Mar 2009


      Is the following code supposed to work (instead of resulting on a stack
overflow)? If so, what I'm doing wrong? I'm using Boost 1.37.0 on MS
Visual Studio 2008, Windows.

#include <boost/thread/once.hpp>

boost::once_flag initialization_flag = BOOST_ONCE_INIT;

void call_me_once()
{
	boost::call_once( initialization_flag, call_me_once );
}

int main( int, char*[] )
{
	boost::call_once( initialization_flag, call_me_once );

	return 0;
}

Additionaly,

- Can a once_flag be safelly used in a class or local static?
- Is BOOST_ONCE_INIT guaranteed to statically initialize the flag?
