subject: Q: User specific data in window classes

From: steve{at}pil.dssd.fido.de (Steffen Offermann)

And yet another question ;-)

When I define an own window class I can use the parameter 
from WinCreateWindow() to convey specific data needed by this class.
For example a structure holding values such as number of rows and
columns and current cursor position if the window is a terminal
window. So far, so good. The problem is: A pointer to this info record
is only available with the WM_CREATE message, not with WM_DESTROY, if
the documentation is right. So there is no clean and comfortable way
to have the window procedure dynamically (de)allocated this record.

My question is: Is it possible to query the record pointer using
some PM API call?

Thanks for any answer,
Steffen
