Here's a question to the GEM/AES experts out there. I'm trying
to use the object type G_USERDEF which is associated with the
following structure (MWC 3.0) :
typedef struct {
long ub_code;
long ub_parm;
} USERBLK;
I've constructed the tree which incorporates a user-defined object
and I have the object calling some VDI routines when I execute
objc_draw on the tree. So in effect it works.
My question (finally) is : how do I get a hold of ub_parm which is
supposedly a pointer to the parameter you want passed ? It would be
very useful to me if I could have a pointer passed to the routine pointed
to by ub_code. I can't figure out how this works.
Thanks in advance
