Create / call librsync for Windows from Delphi 2010

I am currently using windows rdiff port from my delphi 2010 application to compute delta / signature for remote delta / diff

I am trying to investigate the possibility of using librsync library instead of rdiff , I googled and read a lot, I found these files (they can be found / installed using cygwin - librsync-dev-0.9.7-3):

cygrsync-1.dll
librsync.a
librsync.dll.a
librsync.la

      

        
        
        
      

    

However, it is not clear at all how to call this dll (assuming it is possible!)

Does anyone know how to call librsync / cygrsync-1.dll from Delphi 2010?

Thank!
