Passing struct and struct[] into a template
Hi,
I have a template function, and I want it to do something if the
input variable is a list of structs, and something else if the
input is a struct.
1) What's the best way to test this? I suppose I can call
__traits(identifier, results) and look at the last two characters.
2) If `T` is a list of structs, how can I initialize a new struct
so that I can append to `T`?
This is sort of how it might be done in python. I haven't
implemented question 2 yet since I'm not sure how atm:
template Uks(T) {
T query(string q) {
T result;
try {
ulong test = result.length; // won't compile for
non-list structs
// append to a struct list
T.subtype newResult; // is there a function like this?
result ~= newResult;
} catch {
// assign the struct members directly
}
return result;
}
}
I would like to call it like either of the following, depending
on if I want 1 result or X results:
auto res = Uks!(U_Struct).query(email);
auto res = Uks!(U_Struct[]).query(email);
I'd be happy to hear better design methods.
Thanks

I intentionally did not port the Derelict3 GLU binding to DerelictOrg because it uses parts of the deprecated OGL API and is considered legacy these days. Initially, I didn't include support for the deprecated OGL API either, but there were enough requests for it that I finally added it. I have no intention of adding GLU, though. It's easily replaceable.

Interesting. If you de-reference the pointer and assign it back,
do you get back the keep-alive? Like, in the receiving thread:
void threadFunc()
{
receive((Tid cli, immutable(Message) *m) {
immutable(Message) msg = *m; // ---
int retCode = do_something_with(msg);
send(cli, retCode);
});
}
I assume that even if so, there is a race condition there. You
would need to keep the original reference alive until at least
the msg = *m assignment happened, right?
Or... could you tell the GC to leave the memory alone until the
thread gets it? Like in the sending thread:
Tid tid = spawn(threadFunc);
auto p = cast(void*) msg;
GC.addRoot(p);
GC.setAttr(p, GC.BlkAttr.NO_MOVE);
send(tid, thisTid(), msg);
//...
Is that possible? Is it efficient enough to do if you're sending
lots and lots of messages?
Thanks.

I'll summarize what my friend is saying.
netsh is potentially going away. Don't use it if you can.
Since you are using a localized system it, it may be causing issues for
the interface name.
Internally to Windows, it does not use the interface names. It uses id's.
Oh and most importantly use Windows API not netsh.
You should instead be using ConvertInterfaceAliasToLuid[0] to get the UID.
There does not appear to be a c-function to disable/enable an interface.
Supposedly[1] could be used to enable/disable the card which provides
it. Although I would recommend against it.
Lastly, this is half good news and half bad news. We have found a way[2]
through WMI/COM to enable/disable them. Although I've never gone the
path of COM let alone WMI which could be a rather mess to deal with in
D. May be easier to use PowerShell for this.
Either way, my current theory revolves around Windows kernel +
subsystems not liking it toggling so frequently. Friend is a little more
conservative on it.

Don't use it if you can. Since you are using a localized system it, it may be causing issues for the interface name. Internally to Windows, it does not use the interface names. It uses id's. Oh and most importantly use Windows API not netsh. You should instead be using ConvertInterfaceAliasToLuid[0] to get the UID. There does not appear to be a c-function to disable/enable an interface. Supposedly[1] could be used to enable/disable the card which provides it. Although I would recommend against it. Lastly, this is half good news and half bad news. We have found a way[2] through WMI/COM to enable/disable them. Although I've never gone the path of COM let alone WMI which could be a rather mess to deal with in D. May be easier to use PowerShell for this. Either way, my current theory revolves around Windows kernel + subsystems not liking it toggling so frequently. Friend is a little more conservative on it.

However, I'd like to put the emphasis on the fact that it looks like a deterministic way to crash windows, even if to run the script, admin rights are necessary. Now there is also other questions in background: DHCP server, network interface driver even if nowadays they are all in 'user mode', (versus kernel mode).
