FriendlyName on Device
Leo C.
I am retrieving metadata from ThisDevice and ThisModel (such as in the
"describe" example). When testing with WS4D server, there are no
problem, but when I used SOA4D server the FriendlyName was not
displayed.
In my code I followed the "describe" example to get the FriendlyName
like this :
if (ThisDevice.__sizeFriendlyName > 0) && ws4d_locstring_get
(ThisDevice.FriendlyName, ThisDevice.__sizeFriendlyName, "en"))
{
friendlyName = ws4d_locstring_get (ThisDevice.FriendlyName,
ThisDevice.__sizeFriendlyName, "en");
}
I realized afterwards that SOA4D servers may not use English as
language but just French, so I gave this a try :
if (ThisDevice.__sizeFriendlyName > 0)
{
friendlyName = (ThisDevice.FriendlyName)->string;
}
and it worked for both WS4D and SOA4D servers, but I don't think this
is the right way to do it.
Here are my questions :
Is there only one language for each device? and if not, what is going
to happen with my last example?
Is there a way to get the language(s) of the device in order to use my
first example?
And finally, I didn't find anything in the reference manual about
"__sizeFriendlyName", I assumed that it was the number of languages.
Is that right?

No, there can be any number of languages. And your example will always
return the first example.
The friendlyName element is a dynamic array
(http://www.cs.fsu.edu/~engelen/soapdoc2.html#tth_sEc11.11) - the way
gsoap maps elements with maxOccurs=unbounded. The __sizeFriendlyName
gives the number of elements in the array. The array consists of
structures of
http://trac.e-technik.uni-rostock.de/projects/ws4d-gsoap/browser/trunk/include/ws4d_localizedstring.h#L33
. You can look at the code in
ws4d_locstring_get()
http://trac.e-technik.uni-rostock.de/projects/ws4d-gsoap/browser/trunk/src/libdpws/ws4d_misc.c#L38
to see how to work with such arrays.

I think it is better to be able to iterate all languages. I can add
function/macro like ws4d_locstring_foreach(string, lang, it, locstring)
to ws4d-gsoap.
I created a ticket for this feature, but can't promise implement this
soon. http://trac.e-technik.uni-rostock.de/projects/ws4d-gsoap/ticket/104

Yeah, that is specific to gsoaps dynamic arrays.
