AW: Question about usage of HText-Callbacks - Have a very specific problem ...

Hey, Raffaele ;)

I think you know the documentation about 100% better than me ... or better
said not only the documentation.

I read about this function in documentation. Looks good. But I think it's
to late for me to understand this concept in detail.
Therefor I've got another question.

Okay, after looking for some minutes into the documentation I generated this
in mind:

In my main()-function I set a context via HTRequest_setcontext(void*). This
context may I retrieve in HText_new (which I may register as a callback for
creation of HText-objects). Okay. No problems until here. Via the context
(I get it via void* HTRequest_context()) I may construct any memory
structures
I want. Okay. But how may I access this structures in a callback e.g.
addText ?
addText receives an HText* text. But I've no access to the HTRequest-object
...

Have I a problem understanding or am I to bad to
read the documentation correctly ?
[ or is it to late ... after 10 hours programming ? ]
