Class	Description
Signal	This class allows to manage POSIX signals.

For more information about signals, see http://en.wikipedia.org/wiki/Signal_(computing).

Signals interrupt processes, but as Gambas is single-threaded, you will receive them from the event loop.

So, if you are using the SLEEP instruction for example, you will never see them.

Examples

Public Sub Application_Signal(Signal As Integer) Print "Don't do that: I don't want to die during my sleep!" End Public Sub Main() ' Ignore the signal sent when you hit CTRL+Z in a terminal Signal[Signal.SIGTSTP].Ignore ' Catch the signal sent when you hit CTRL+C in a terminal Signal[Signal.SIGINT].Catch ' Sleep one hour :-) But do not use the Sleep instruction, otherwise you won't see the signal! Wait(3600) End
