Re: [Boost-users] condition_variable::timed_wait doesn't wait

I haven't used boost's locking mechanisms yet, but POSIX condvars don't protect against spurious wakes. Thus,

[snip]

...

//wait for an answer.. bool ready = _cond.timed_wait(lock, xt, boost::lambda::var(_data_ready));

you probably want this in a loop,

while(!_data_ready) { _cond.timed_wait(... _data_ready); }

timed_wait with predicate (that's what OP used) does exactly this, it waits on condvar until predicate is satisfied. So problem is in some other place. Roman.
