Identyfikator procesu.

Witam, mam krótkie pytanie - jak mogę zdobyć pid jakiegoś procesu, za pomocą jego nazwy?
Da się to zrobić jedną funkcją?

Z góry dziękuję za pomoc.

Coś nie tak, pojawiły się takie błędy:

Zapomniałem dodać że korzystam z code blocks.

Noś zapomniał, bo mingw nie wspiera wstringów. Zamień je wszystkie na stringi, i tak pewnie makro UNICODE nie jest zdefiniowane i wywoływana jest wersja ANSI.

Okey, wielkie dzięki, działa.
