Even more dumb regression questions...

[Geoffrey Hausheer]

InitiallyI thought I'd start with writing a test in Perl, 
and I got some basic stuff working. But then I needed to 
access structures, constants, etc, and had no idea how to 
do this, so I am now rewriting my test in C.  My 
understanding was that for the most part, the C and Perl 
testing infrastructure were supposed to be comparable, but 
I haven't seen any examples of how I can do the things I 
mentioined (specifically, access constants (flags for 
functions), or create/read structures required by 
functions.

Is this possible to do, and if so could someone give me an 
example of each?  The constants are obviously less 
difficult, in that I could always redefine them in the 
test, but being able to manipulate structures seems like 
it would be a requirement for the framework.

Sorry if this is all really straight forward.

Thanks, 
.Geoff

You can get the constants by doing 'use xxx;' where xxx is the name
of the C header that would contain the constants in C. Dor instance:

use winbase;
use winuser;

For structures... there was a perl sample that created a Windows that
was floating around. But I cannot find it anymore. Does anyone know
where it is?

If I remember correctly you are supposed to 'pack' the data so that
its layout matches the C structure (and unpack it to get the data). I am
not certain if there were plans to provide macros to do this.

Found it again. I attached it so you can have a look at it. But note
that it is based on a very old version of the framework. For instance:
 * it should not worry about wine::declare and define all the
constants itself but instead do:
   use winuser;
   use user32;
 * it should not use printf but ok and trace.

Still, it shows how to 'pack data into a structure' and how to
declare callback procedures in perl. These are two useful items that
were not in my presentation. About packing data-structures, I don't know
if it has been simplified since...
