[REBOL] Re: Pointer to an unknown [struct!]

Hi Maarten,
I'm not sure if I understand your problem, I don't know what should look
your structure but this is little example how to get pointer to a structure:
number: 123
p_str: make struct! [str [struct! [num [integer!]]]] reduce [number]
>> probe third p_str
== #{202FD800} ;this is a pointer to structure containing integer
regards,
Cyphre

Subject: [REBOL] Pointer to an unknown [struct!]
Hi,
Tinkering with the library interface I have the following problem:
I must pass in a pointer to a result structure (specifically: LDAPMessage
from
the Openldap libs). I have no definition for the structure however, as
clients are "not supposed to directly manipulate these".
I must pass it a zillion times around instead, which should not be a
problem
if I'd knew how to do the initial memory allocation.
Anyone?
