[03:57] <reduz> yessopie, so i don't havemak to rely on unicows
|
|
[03:58] <yessopie> reduz- yeah, all of the functions fail, and then you can call GetLastError () which will return 120
|
|
[03:58] <drumstick> CategoryApl, hehe, what? :)
|
|
[03:59] <CategoryApl> didn't Verona lead to some trouble
|
|
[03:59] <yessopie> 120 = ERROR_CALL_NOT_IMPLEMENTED
|
|
[03:59] <yessopie> (you can use that constant if you include winerr.h)
|
|
[03:59] <CategoryApl> well answer with winning a compo
