I am just trying to use modern POSIX API's to improve portability
Well... modern has come to mean less portable in my book. (I like using modern APIs, but they tend to break grgrgr.)
(and functionality in this case). For example, by using sigevent,
one doesn't need to have global variables and he can pass the struct
he wants to modify in the signal. In addition, one can use the
monotonic clock, which is immune against time changes, and also
use timespec which is more precise. Finally one is not limited to
sigalrm for timers, but can send any signal.
Thanks.
I am really suprised
that OS/X does not have them; I would have expected it to work on
more systems than it does currently...
I could only check with Snow Leopard and there is no timer_t there. I don't have access to Lion at the moment; when I do, I'll check again. If there is no support in it, I'll have to implement some conditional logic to use the new timers only if available (unless you have a better alternative?). If there is support, then I won't care about backwards compatibility.
