The existing versions are certainly slim on memory, but use malloc, which may cause memory leaks if the person on the application side isn't careful freeing things, or cause performance issues, or just cause plain failures in low memory embedded systems... > The original plan was to have a separately maintained > userspace library to do things 'properly'.

There are some features which we use to "self-discover" the installed devices/drivers. return a string of names handle unsigned ints in the read/write functions Some minor stuff. > The networking stuff in particular > might introduce some non kernel dependencies that may or may not be a > problem. Ack - I think that sits beside yours. iio_utils_attach.h and the network one is iio_utils_net.h (ot something like that). It's the same structures, similar function names, it's does it include a IP address, or a path... > > Is there a list of other things people want to see from userspace? [2] > > Nope.
