As far as I know stdout is always available for Linux. Even if I compile
applications for X11 and launch them from a desktop icon, I can do
writeln() calls without problems (unlike under Windows which will throw
an error).
No, the application can (for instance almost all daemons do) close stdout.
Programs that use ncurses will also be messed-up.
For CGI programs, stdout is also reserved for the HTML output.
Imagine someone else's code doing a beep, and it ends up in your
HTML output.
Before you think that these are far-fetched:
If you'll remember, tiOPF had some very common (but nasty) windows-only
constructs like showing message boxes deeply buried in core functionality.
Works fine. Till I come along and want to run the thing on Linux. Bummer...
By that rationale: no beep() on linux.
Michael.
