Sleep() ?

I have to wait in a loop until some condition is true.
What I want is to have some function that doesn't take the resources
while waiting.

Thanks for any suggestions.

Take a look at wait_for_data_to_process() function in
http://www.boost.org/doc/libs/1_37_0/doc/html/thread/synchronization.html#thread.synchronization.c...

There is no standard c++ way of doing. Depending on your OS and the
reactivity requiered you can wait for a signal (see conditions in POSIX
thread by example, sleep (in preemptive OS) or release the processor (in
cooperative OS).

I think that external library (50MB) is maybe a overkill for just this
one task.
Is there some other solution?
