BTW, somewhere I "wired in" TADNS (http://adns.sourceforge.net/) so = libtask's network lookups didn't block.

Let me know if= you have any interest in me cleaning it up for use.

Russ implemented his own setmcontext= and getmcontext functions
to work on systems that doesn't properly support ucontext.
So I don't think you really need ucontext support in your libc.

By the way, I maintain an updated version of libtask:

https://github.com/0intro/libtask

I've used it on quite a few places over the years,
but I only on POSIX systems so far.

One other thing that I've looked at but never used is = Adam Dunkels' "protothreads" (http://dunkels.com/adam/pt/) although you'd still need to = roll your own channel library.

The = system I am trying to add libtask to has no runtime other than libc.

Corrently it is an even based system that uses a "min main loop" = and
a twisty maze of nested state machines that all look the same.

Hence my desire to add co-routines + channels (i.e. exactly what libtask is= )
to it. I have no need for the file or network modules but those are easily = removed.

I don't have the context calls but I do have setjmp/longjmp so that is = what I
am trying to use.

I will shout if it works out.
