2144	boost::thread constructor wants to make copies of the argument	mmikucionis@…	Anthony Williams	"Hi,

I noticed that boost::thread constructor makes a copy of its argument.
Suppose I have a big structure that I use as thread context and I don't want redundant copies on stack or anywhere else.

For example:

struct foo
{
  void operator()()
  {
     // zzz
  }
private:
  foo(foo&); // no copying, please
};

boost::thread(foo()); // this fails due to private copy constructor

I bumped into this problem when I included boost::thread itself into the structure (forbids copying too ;).

Thus I wonder if the argument could be replaced by a reference to an argument which would not insist on copying things.

As a workaround I do the following now:

void bar(foo *ptr) { (*ptr)(); }
boost::thread(boost::bind(bar, new foo));

I looked at repository on the web and I could not find class thread anymore (moved somewhere else since 1.35?), so maybe it's already fixed...

Thanks for great library!"	Bugs	closed	Boost 1.36.0	thread	Boost 1.35.0	Optimization	wontfix
