Re: [avr-gcc-list] libc.a & fread

You are right. Those functions are not supported.

Why ? The answer is very simple. We have a standalone
controller without any file system and without device
drivers for console, etc....

So those calls cannot be present.

I am working on a OS for a longer time now (months by
month I have no time to continue), but my OS should
become open source.

The point of my OS in contrast to others:
I want to have a standard POSIX conform interface AND
and real socket interface, so that the programming
model is similar to Linux and other UNIX systems !

Of course, it will be only a subset of all functions.
But it includes multitasking, of course, and a 
protocol stack for LAN!
