[Boost-users] Question about boost::once

Hi everybody, I need to use the boost::call_once function defined on the boost/thread/once.hpp file. I need to pass 2 arguments to the function I call once but boost::call_once only takes void (*func)() as argument. Boost::bind won't help me here I think since what I need is not a functor. I need something that can be passed to call_once as a void (*func)() but where I can pass parameters. Anyway, any help on this would be greatly appreciated. Also, any other way to call a function once in a multithreaded environment just like boost::call_once does would work for me. Thanks -delfin
