May 04, 2004 [Buglet] sleep() method is seriously large-grained | ||||
---|---|---|---|---|
| ||||
the std.c.time.sleep(x) method argument is actually in *seconds*; this is really not very useful <g> Can we get it changed to represent ms instead? That is; use SleepEx() rather than Sleep() on Win32 ... (I know many of these functions don't guarantee granularity below around 20ms, but that's much better than a granularity of 1000ms :-) - Kris |

That way: - there'd be no need to change every existing program so that it doesn't run 1000 times too fast - when an API function comes along that takes microseconds, it'll fit in neatly with Phobos as it stands. At that point, the millisecond'll be a rather arbitrary choice of unit. The second, OTOH, is the basic SI unit of time, as well as being a unit in which most people are likely to think, and so remains a reasonable choice.

It is in std.c. This means that it is an interface to the C RTL. So unless the RTL changes, std.c.time.sleep isn't going to change. Still, we can always invent a new function with the semantics I've suggested....

Posted in reply to Stewart Gordon | Wait! I take it all back. If I'd bothered to read a bit further I'd have seen the unix-style msleep() and usleep(). Sorry :-( I marked it as a buglet since I imagine it was actually *meant* to be ms ... I've never seen a runtime library sleep() function that doesn't get any finer than 1000ms intervals. It's almost worthless as it is <g> Naturally, there's a first time for everything. The fact that it's still that way may indicate that no-one has really used it yet? It's certainly not used in any of the phobos code. The windows.d has this instead: export void Sleep(DWORD dwMilliseconds); But that's not portable. - Kris "Stewart Gordon" <smjg_1998@yahoo.com> wrote in message news:c78hoc$kmg$1@digitaldaemon.com... > Kris wrote: > > > the std.c.time.sleep(x) method argument is actually in *seconds*; this is > > really not very useful <g> > > > > Can we get it changed to represent ms instead?

They're optional portions of POSIX.

Oops... and I thought I was replying to a recent post :-)
