[avr-libc-dev] 1.4.5 question

[Steve Franks]

Howdy,

I see:

" The macro 
fdev_setup_stream()<http://www.nongnu.org/avr-libc/user-manual/group__avr__stdio.html#gf41f158c022cbb6203ccd87d27301226>is
provided to prepare a user-supplied FILE buffer for operation with
stdio.
If floating-point operation is desired, a user-supplied buffer can as well
be passed for the internal buffering for the floating-point numbers (and
processing of %[ scanf data)."

has appeared in the libc docs.  I was wondering about the "as well ... for
the internal buffering" part - this is new, no?  I seem to be having malloc
issues with sscanf(%f), so now is a good time for me to get rid of malloc
anyway, as our code is not using it.  I read pretty much all the related
items I could find in the libc manual, and saw no mention of how this might
be done.  I presume the fdev_setup stream examples are just for the uart
i/o, and not for the floating point buffer - right?

Thanks as always,
Steve
