Question about IPC between WINE and other processes

[dd jj]

Hello Roderick,
 
Thank you for your answering.
Actually, now I am trying to use WINE to port an windows application to linux.
But if I use program loader provided by WINE to directly run the exe file under linux,
some of the functionalities are involved with IPC between WINE and other local
X processes, which is not supported by WINE.
 
So, I need to rewrite the local codes for them, as Mike explained before,
 
"What you can do is rewrite only the parts that need rewriting and turn
them into shared libraries. Then you can use WineLib to combine the
Win32 code and the Linux code into one program."
 
Here, I am glad to learn from you there seems a more easy way:
(As my understanding, the other way you mentioned is the same one as Mike's)

"An easy way is to put this 
X functionality in a winelib dll. This dll can then be used by your app. The 
advantage of a winelib dll is that it can use win32 api's but also native 
Linux api's."
 
Could you please make sure whether this method can meet the need to "find any process's window info", not only "windows under WINE" ?
 
And could you please give some more implementation details about that?
 
Thanks a lot!

Hi,

As I understand it you have a Windows app that needs to have access to some X 
stuff. To access that you somehow need to extend your app with some X 
functionality. There are several ways to do that. An easy way is to put this 
X functionality in a winelib dll. This dll can then be used by your app. The 
advantage of a winelib dll is that it can use win32 api's but also native 
Linux api's. The other option is to completely build your app using winelib 
and also add the native code. Personally I think the dll is the easiest way.
