Hello everyone, I've been fascinated by D lately and have been using it
for all
my school assignments (like simple ray casting and simulated annealing).
What I can't find anywhere is how to do something like
"signal(SIGINT, myhandler)" (I'm in a Linux environment).
I need this to stop the annealing process early but still keep the
current best
result. Is there a better way to interrupt my program?
Thanks!

P.s. I hope I sent this to the appropriate address. :)
Hi!
I don't know of any official way, but since D links against the c
runtime you can just hook up functions from there, I believe. This works
on osx at least:
import std.stdio;
extern(C) void signal(int sig, void function(int) );
// Our handler, callable by C
extern(C) void handle(int sig){
writeln("Signal:",sig);
}
void main()
{
enum SIGINT = 2; // OS-specific
signal(SIGINT,&handle);
writeln("Hello!");
readln();
writeln("End!");
}
$ rdmd sig.d
Hello!
^CSignal:2
^CSignal:2
End!
