           Summary: writef and friends won't read/write from/to redirected
                    std handles
           Product: D
           Version: 1.009
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: jascha at mainia.de


on win32 writef and friends don't use redirected std handles if they are piped.
stdin/out/err handles 0, 1 and 2 are not the redirected versions on win32. one
needs to get redirected handles with
GetStdHandle(STD_INPUT_HANDLE);
etc.

therefore, the std handles from std.c.stdio used in std.stdio probably cannot
be constant.
