[Xcb] Question about xcb_list_fonts_with_info

[Jochen Keil]

Hello,

I have a question regarding the `xcb_list_fonts_with_info` request function.

The Xlib function `XListFontsWithInfo` returns an char ** array which I
can walk through by taking `count_return` into consideration.
When I try it out with e.g. maxnames = 8 and pattern = "*" I get a list
with 8 null-terminated (\0) strings of fonts available on my system,
starting with the very first.

How would I do that using the `xcb_list_fonts_with_info` function?
I can get the very first match with `xcb_list_fonts_with_info_name` and
`xcb_list_fonts_with_info_name_length`, but how would I go about for the
rest?

I tried forwarding the pointer returned by
`xcb_list_fonts_with_info_name` with
while (*font != '\0') { ++font; } ++font;

This does not work. There is only garbage after the first font string.
However, I'm not sure if it's the xcb_fontprop_t struct or just random,
unallocated memory.

Is there a way to get all of the font strings? I think this should
probably be a variable field and not a fixed one, together with a
xcb_str_iterator, like for xcb_list_fonts.

Thank you and best wishes,
Jochen
