Visualizing the output of concurrent threads

Visualizing the output of concurrent threads

[Manuel Carro]

    Hi.  I need to visualize the output (consisting of strings) of
several (not too many---say around 20) concurrent tasks separately.
Letting the output mix in the same screen will not be useful.  I
suppose this is not too difficult to do, but, has anyone done it
already?  It doesn't need to be anything fancy, just plain I/O in
separate windows or in separate regions of one window, one
window/region per task.  The only thing is that I'd need it both for
Linux and for Windows (possibly using different graphic libraries in
each case).

    Thanks for any reply!

One of the *very* first Claw demo programs did that :)  Nowadays I
just use a package called TTY_Out:

package TTY_Out is
  type TTY_Type is new Claw.Basic_Window.Basic_Window_Type with private;
  procedure Put(TTY  : in out TTY_Type;
                Text : in     String);
  ...

Presumably something similar can be done with one of the multi-OS
systems.
