Indeed, funopen() is a bit of a sledgehammer; all the rest of stdio could be removed without losing any power (just convenience). I actually prefer funopen() in most respects. In particular, it allows things like printing into mallocked storage without having to impose a length limit (which naive use of snprintf and strdup does). stdio has desperately needed something like funopen() for a long time. It was so egregiously missing that I hacked it into the 4.3 stdio back when I was working with 4.3...I called it fopenfxn() and the interface was a bit different, but it was basically the same idea. der Mouse mouseat_private 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
