[lhw]

hello guys,a couple of days i ask help for my readcd GUI from thanks Wakillon for his capturing stderr output solution ,But it wont get all datas and wait a long time if handle a bigger CD,

i just thought is it possible get dynamic size of a file during its generated via a working process ,it could be a solution for sending datas to a progressbar if possible, after couple hours searching i'm still can't get the pointer and i'm not sure it make sense ,really need help on this ,your help is always appreciated.
