Signals

[Sascha Ziemann <szi aibon ping de>]

Hi,

it would be nice to be able to send signals from one application to
another.

Example: You have a master application with some toggle buttons and some
client applications. Each client is connected to its toggle button.
Pressing the toggle button should start the client, releasing the toggle
button should close the client. But if the client closes itself, the
toggle button needs to be released, too. This requires some messages
between the master and clients.

I think it not very difficult to use Sys V IPC messages to send signals
between applications. Is anybody here, who did already something
similar?
