/* DDE message exchange
*
* - Session initialization
* Client sends a WM_DDE_INITIATE message, usually a broadcast message. lParam of
* this message contains a pair of global atoms, the Application and Topic atoms.
* The client must destroy the atoms.
* Server window proc handles the WM_DDE_INITIATE message and if the Application
* and Topic atoms are recognized sends a WM_DDE_ACK message to the client. lParam
* of the reply message contains another pair of global atoms (Application and
* Topic again), which must be destroyed by the server.
*
* - Execute
* Client posts a WM_DDE_EXECUTE message to the server window. lParam of that message
* is a global memory handle containing the string to execute. After the command has
* been executed the server posts a WM_DDE_ACK message to the client, which contains
* a packed lParam which in turn contains that global memory handle. The client takes
* ownership of both the packed lParam (meaning it needs to call FreeDDElParam() on
* it and the global memory handle.
* This might work nice and easy in Win3.1, but things are more complicated for NT.
* Global memory handles in NT are not really global, they're still local to the
* process. So, what happens under the hood is that PostMessage must handle the
* WM_DDE_EXECUTE message specially. It will obtain the contents of the global memory
* area, repack that into a new structure together with the original memory handle
* and pass that off to the win32k. Win32k will marshall that data over to the target
* (server) process where it will be unpacked and stored in a newly allocated global
* memory area. The handle of that area will then be sent to the window proc, after
* storing it together with the "original" (client) handle in a table.
* The server will eventually post the WM_DDE_ACK response, containing the global
* memory handle it received. PostMessage must then lookup that memory handle (only
* valid in the server process) and replace it with the corresponding client memory
* handle. To avoid memory leaks, the server-side global memory block must be freed.
* Also, the WM_DDE_ACK lParam (a PackDDElParam() result) is unpacked and the
* individual components are handed to win32k.sys to post to the client side. Since
* the server side app hands over ownership of the packed lParam when it calls
* PostMessage(), the packed lParam needs to be freed on the server side too.
* When the WM_DDE_ACK message (containing the client-side global memory handle)
* arrives at the client side a new lParam is PackDDElParam()'ed and this is handed
* to the client side window proc which is expected to free/reuse it.
*/
/* since the WM_DDE_ACK response to a WM_DDE_EXECUTE message should contain the handle
* to the memory handle, we keep track (in the server side) of all pairs of handle
* used (the client passes its value and the content of the memory handle), and
* the server stored both values (the client, and the local one, created after the
* content). When a ACK message is generated, the list of pair is searched for a
* matching pair, so that the client memory handle can be returned.
