When posting DDE messages via PostMessage(), an application first calls
PackDDElParam() and sends its return value (a pointer cast to LPARAM) as
the lParam in PostMessage().
Normally the receiving application is responsible for freeing the structure
[via FreeDDElParam()]. However, if the call to PostMessage() fails, the
posting application must free the packed data. This is also the method used
by 16-bit Windows.
