Externally disabling signals for a Linux program

Question

On Linux, is it possible to somehow disable signaling for programs externally... that is, without modifying their source code?

Answer 1

I would suggest that your C (and Java) application needs rewriting so that it can handle an exception, what happens if it really does need to be interrupted, power fails, etc...

I that fails, J-16 is right on the money. Does the user need to interract with the process, or just see the output (do they even need to see the output?)
