X-IsSubscribed:	yes

And ya "Dllexport and Dllimport"  are required in source code???? I
mean should include in my own header files?
I read that ----

""The main problems are caused by the fact that Windows DynamicLinked
Libraries (DLL s) assume some specific information to be introduced in
the source code directly, while the UNIX DynamicLinked share Libraries
don t need any "special information" in the source""

so i have to change source code ???I mean have to add "special
information" like  Dllexport and Dllimport ???

waiting for reply...
