After perusing the archives, what makes the most sense to me is to
launch
a detached shell that executes a simple AppleScript.
The script has a delay of 2 seconds and then simply does a 'launch'.
You're overcomplicating things.
int main(int argc, char **argv) {
if(fork() || fork()) exit(0);
sleep(2);
execl(argv[1], argv[1], NULL);
exit(1);
}
Launch this with a single argument - the path to your application's
executable. It'll background itself, sleep two seconds, and exec your
application.
This is, IMO, a rather bad approach. If your app takes longer than two
seconds to quit, it will fail. It's generally a bad idea to use exec()
on GUI apps. And you end up creating three subprocesses for no
particularly good reason.
The double-fork is to fully detach the child process from the parent -
note that all of the parent processes immediately die, because fork()
returns nonzero.
The point about exec() is entirely correct, though - LaunchServices is
probably the right way to go.
