[Boost-users] [boost::bind] How use with fn objects?

From: BRIDGES Dick (Dick.Bridges_at_[hidden])

The documentation gives examples for
  int operator()(int a, int b)...
  bool operator()(long a, long b)...
that use _1 to represent the first parameter (i.e., 'a').

I'm trying to pass a function object that takes no
parameters to a boost::thread constructor and cannot
get it right.

<my_code>
class Foo {
    void
    operator()() { /* do something */ return; }
}

int
main( int argc, char **argv ) {

    Foo f;
    boost::thread doit( boost:bind<void>(f,_1)() );
    doit.join();

    return 0;
}</my_code>

Isn't the '_1' required for the this pointer?  If it's not
required, what is the correct form?

Thanks in advance for any help.

Regards,
Dick Bridges
