[Xcb] Iter

[Jeremy Kolb]

As much as I enjoy iters a lot of xlib code was written using pointers
and then you could simply use array syntax. I've noticed that sometimes
XCB will generate a function that allows me to do this: it simply
returns a pointer to an array of some structure.  Then when I modify
that structure it decides to only make an Iter function.

For instance:

    <request name="QueryEncodings" opcode="2">
        <field type="PORT" name="port" />
        <reply>
            <pad bytes="1" />
            <field type="CARD16" name="num_encodings" />
            <pad bytes="24" />
            <list type="EncodingInfo" name="info">
                <fieldref>num_encodings</fieldref>
            </list>
        </reply>
    </request>

and
    <struct name="EncodingInfo">
        <field type="ENCODING" name="encoding" />
        <field type="CARD16" name="name_size" />
        <field type="CARD16" name="width" />
        <field type="CARD16" name="height" />
        <field type="Rational" name="rate" />
        <field type="CARD16" name="pad" />
        <!--<list type="char" name="name">
            <fieldref>name_size</fieldref>
        </list>-->
    </struct>

Gives me:

XCBXvEncodingInfo *
XCBXvQueryEncodingsInfo (XCBXvQueryEncodingsRep *R);

int
XCBXvQueryEncodingsInfoLength (XCBXvQueryEncodingsRep *R);

XCBXvEncodingInfoIter
XCBXvQueryEncodingsInfoIter (XCBXvQueryEncodingsRep *R);

However if I change EnocodingInfo:

    <struct name="EncodingInfo">
        <field type="ENCODING" name="encoding" />
        <field type="CARD16" name="name_size" />
        <field type="CARD16" name="width" />
        <field type="CARD16" name="height" />
        <field type="Rational" name="rate" />
        <field type="CARD16" name="pad" />
        <list type="char" name="name">
            <fieldref>name_size</fieldref>
        </list>
    </struct>

I get these:

int
XCBXvQueryEncodingsInfoLength (XCBXvQueryEncodingsRep *R);

XCBXvEncodingInfoIter
XCBXvQueryEncodingsInfoIter (XCBXvQueryEncodingsRep *R);


And now I'm missing that first function and only get an Iter function.
This seems pretty inconsistent to me, and I would really like the
XCBXvQueryEncodingsInfo function both times.

Is this a bug or is it because of the list inside the structure?
