Hi, I had a look at a couple of readline like libraries; editline and linenoise. A difficulty with using them is that they both want fd's or FILE*'s; editline takes either but from a brief look I think it's expecting to extract the fd. That makes them tricky to integrate into qemu, where the chardev's hide a whole bunch of non-fd things; in particular tls, mux, ringbuffers etc.
If we could get away with just a FILE* then we could use fopencookie, but that's GNU only. Is there any sane way of shepherding all chardev's into having an fd? Once you had those then you could also use them in a separate thread. Dave -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
