The described technique use some OS specific features. It can be adapted
to OSX as far as I know, but POSIX do not guarantee to have all required
features to implement this.
That is why I was rephrasing Maxim's statement to mean "UNIX signals
handlers as error mechanism is a complete disaster."
I don't do UNIX system programming at C level since 2002, but my POSIX
memories, is that it is as portable as C, with its share of undefined
behaviors and OS specific extensions.
And if I recall correctly the behavior of what was allowed to do in the
signal handler, and how UNIX/libc functions would behave upon
interruption was not that stable across multiple UNIX variants.
