I do not know what is "longjmp" method :-(

          I do not have a DLL which wants to use the Win32 APIs. I have a
          Linux dynamic library (*.so) which wants to use the Win32
          APIs.

              What is "setjmp" - an assembler directive ? Is
              <startwinelib.so> a standard WineLib application or I have
              to create it myself ?

          :-( What is "longjmp" exactly and how it should look like ?
          Unfortunatelly I'm not familiar with the assembler too much, and
          I know little about Wine :-(

              Is LoadLibrary a Wine feature or Windows feature ?

              This means that I link that magic <startwinelib.so> +
              other Win32 libraries which I need (like -lavifil32) to
              my Linux executable (or Linux dynamic library *.so) and
              everything will work out of box ? But what is the key
              point in this approach ? I do not use any functions in
              <startwinelib.so> - just link it to my Linux application
              and it will work ?!

Thank you very much.
