<p class=MsoNormal>Greetings,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a proprietary library that has both Windows and Linux
ports. The Windows DLL has problems running on Wine, so I have created a
builtin version of this DLL in Wine. This has worked fine, except for one
function that basically creates a new thread and fires back events to the
calling Window application. I believe I have traced this down to the
Linux version of the library creating the new thread with pthread_create.

<p class=MsoNormal> }<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If instead of using pthread_create I use CreateThread, I
never have a problem. I notice no other wine DLLs are using
pthread_create and I have seen hints that this might not work. If so, how
do I use the Linux library. (Call_dll_to_spawn_thread_and_register_callback
is just simulating what the Linux library would do)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Do I create a separate thread using CreateThread to
communicate back to the Window application, so that
Call_dll_to_spawn_thread_and_register_callback effectively creates two threads,
one using CreateThread (Wine DLL), one using pthread_create (Linux Library) and
then do synchronization between the two?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help, suggestion, ideas, questions would be greatly
appreciated.<o:p></o:p></p>
