I think that will not make special work to make additional headings for a call of these functions as dynamic. Now I work over it. We will admit, as HDC I transfer parametre of an operating window in Winuser32. I think will work so: wine-> user32.dll-> startmyconvertor or I must to recompile wine function for my program as libEMF.so... There is like 640 kB, and then is not wine need for working my program.. Only dynamic library. Also, I'm want to ask: what is license of wine ? I'm need to make any information about using wine code. I'm from Russia and we are don't use any license like GPL.
