TIOCSTI or workaround?


I have a program I've writ which takes input and types on to other terminals; however, it seems that under Cygwin, TIOCSTI on a file descriptor doesn't work according to plan -- I get "Invalid argument", but I don't know why.

Did a read on ioctl, and saw something about POSIX STREAMS. I thought that paradigm had died a mean nasty ugly death YEARS back, but I'm hoping that's entirely beside the point.

Does there exist a way to successfully call

	ioctl(fd, TIOCSTI, (char *)cp)

or is there a workaround?
