Re: Re[2]: Prototyping printf()

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Eric,

Why can't you do this?  As long as you ensure that your structures are always 
aligned on a boundary this works fine.  I don't understand exactly what you are 
trying to accomplish, but in our applications the data and procedures that 
support 
them are all dynamically referenced by pointers.  Those pointers are stored in 
user 
spaces.  The underlying process that loads them knows into the user space know 
when a data element contains a pointer and makes sure it is aligned.  The only 
assumption is that a user space will be aligned.

Well Ken I am glad that I am not loosing what little mind I have left
:-)

The main reason I went through this exercise was to try to simulate
some semblance of object orientation by having externally defined data
Structures for the object and then creating instances of them in
memory with pointers to other objects contained within... I have some
of this working :-) But after Barbara's warning that this is not
supported behavior I will have to figure something else out :-(

It would be nice to be able to define a pointer data type externally
:-)
