About this. What about exposing the default loop functions in the ev
namespace?
Like:
ev::init (flags) -> ev_default_loop (flags)
ev::get () -> ev_default_loop (0)
ev::loop (flags) -> ev_loop (ev_default_loop (0), flags)
ev::unloop (how) -> ev_unloop (ev_default_loop (0), how)
ev::post_fork () -> ev_default_fork ()
ev::destroy () -> ev_default_destroy ()
ev::count () -> ev_count (ev_default_loop (0))
ev::backend () -> ev_backend (ev_default_loop (0))
etc., etc., etc.
I'll keep the default loop struct wrapper too, because in a multi loop
environment let you use a callback for a default or a dynamic loop
indisticly, like:
void cb (watcher &w, int revents)
{
w.loop.unloop (); // I don't care if is the default or not.
}
So you can reuse callbacks. You can also use automatic destruction for the
default loop:
{
ev::default_loop l;
// ...
// bye, bye, l gets destroyed
}
But you can avoid it:
ev::init ();
ev::loop ();
And you have more concise way to use the omnipresent default loop, like
you can do something like:
ev::count ();
instead the longer:
ev::get_default_loop ().count ();
The struct wrapper could be avoided for EV_MULTIPLICITY=0 too.
What do you think?
PS: The "big" problem comes with ev::now () =P
