iOS Can I use signal(SIGINT, SIG_IGN)?

[mikezang]

I try to use some UNIX library in iPad, but I am not sure if I can use all of functions.

For example, signal(SIGINT, SIG_IGN);

I want to know if I can't use it, can I use some alt methods to do the same functions?

Well, I just comment those code, now I got what I need.
