Hello Boost Users,

I'm trying to learn multi threading in C++.

http://www.boost.org/doc/libs/1_39_0/doc/html/thread/thread_management.html

says

"Objects of type boost::thread  are movable, however, so they can be stored in move-aware containers, and returned from functions."

Please help me understand what are movable objects.

Moveable objects are objects supporting move semantics. See

http://en.wikipedia.org/wiki/C%2B%2B0x#Rvalue_reference_and_move_semantics

for a rather dry account of move semantics, or probably better see

http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/

where Dave A tells us all about it.

HTH

- Rob.
