kako dll? /c++

Zanima me kako narediti *.dll knjižnico. So kakšne posebnosti pri definicijah, deklaraciji, kodi(ključne besede)... In kako to prevedeš(compajlaš).Kako jo lahko povežeš v program?
Dober bi bil tudi source *.cpp(*.c) in *.h fajlov za knjižnico in program,ki to uporablja.

Upam, da ti tole pomaga.
Ce ti ne DLL ni zate. Ce uporabljas za svoje programe, se ponavadi DLL ne pise. Zapec vse v EXE.

Ce pa hoces modularno delat programe delaj s COM objekti. Ti vsaj ne bo treba EXE datotek zmeri prekompajlat, ko bos dll spremenu.
