Whileprogrammers can explicitly create threads, much of the work of handling threadsis taken care of behind the scenes by the operatingsystem ... window) is taken care of by the operating system. You’llbe even more pleased to find that for some system messages, even the window’sresponse to the message is handled by the BeOS. For instance, ... and moving of windows is handled by the system, not by the SimpleApp code.This simple demonstration emphasizes the power of the BeOS system software—itis the system software code (rather than...
