Yep, on windows GetStdHandle doesn't always return the same kind of handle depending on the context: - if the output/input is console, it is console handle (i.e. need to be manipulated through console function) - if the output/input is a pipe, it is a pipe handle (i.e. need to be manipulated through pipe function) And since we are in the good old world of windows, the return type is an HANDLE whatever it is ;-) I think your issue is related to this difference. It can be fixed, but you need a little bit of knowledge about windows pipe/standard handle. Regards, Sylvain Le Gall _______________________________________________ Caml-list mailing list.
