Re: Fiber thing?

Fun, fun, fun:) I figured it would take a pair of SJ/LJ per context switch
and that was about it. 512 bytes to be copied per switch on Win32. Somehow I
don't think non-preservation of locals is a big deal.I might try to run this
puppy one of these days just for the fun of it.

Thanks a lot,

For more on setjmp/longjmp fibers
please look at the following page:

http://www.csl.mtu.edu/cs4411.ck/www/NOTES/non-local-goto/mtp.html

It describes a scheduler written in ANSI C using only
setjmp and longjmp. It has one major deficiency,
that is, it does not copy the stack. So you cannot use
non-static local variables in the functions that are
running in parallel as coroutines/fibers.

But, perhaps it is possible to perform this feat with
just plain ANSI C. Is anyone here courageous enough to try?
