Update: Something about this post "tweaked some go-buttons", I don't know why, but I think further posts make what I intended very clear. I can just strike this without changing the advice.

Alexander, Perl provides the basic signal functions on Windows meaning emulate.

The OP was asking about CTRL-C.
And I provided some code that runs even on Windows! Although the question was not about Windows.

If the question is about Windows specifically, lets start a new thread about it.

My advice and code stands for *nix also.
