well, the C-pointer-type of <C-signed-char> was automatically generated
by melange. The <C-string> has the nice possibility to be able to pass a
Dylan <byte-string> to C-FFI functions which expect a <C-String>. The
conversion (append 0 byte) is done automatically. This is not the case
with <C-signed-char>.
So, since <C-string> is magic and convenient, we use it here. Also,
<gchar*> (most often used in GTK API) is a <C-string>.


King Regards,

Hannes
