programmers can explicitly create threads, much of the work of handling threads

be even more pleased to find that for some system messages, even the window’s
response 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—it

... the
control (typically by clicking on it, as for a button), the system passes the applica-
tion-defined message to the window. How the window handles the message is
determined by the code you include ... the
BTextControl constructor, and is then edited by the user. The contents of the
editable field can also be set at any time by your program by invoking the
BTextControl member function SetText(). ... a control, the system responds by sending a message to
the window that holds the control. This message indicates exactly which control
has been clicked. The message is received by the window’s...

errors processed by the operating system, processes need not contain code to catch ... either the user job or the operatingsystem itself. Describe
