Freeing PackDDElParam() Memory

Last reviewed: November 2, 1995
Article ID: Q94149

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) versions 3.1

Microsoft Win32 Application Programming Interface (API) included with:

    - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

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.
