It would appear (from reading the doco) that Fibers in Win32, would
allow a fairly easy implementation of C coros for Lua. These APIs
are fairly close to ucontext and could emulate the ucontext suite
of functions. See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/fibers.asp
Fibers are supported for 98/me and NT3.51 forward. Sorry no WIn95.
So, for recent *nix and Win32 there would seem to be a way to implement.
The older Unixes represent a bit of a problem. Would it be viable to
implement C coroutines for Lua only for recent Unix and most Win32
platforms?
I guess this would mean something like
require 'coroutine'
would be needed to use coroutines.
At Lua build time it would not be too difficult to engineer a process that
only builds the C coro support if ucontext or fibers are available.
Is this sort of approach acceptable?
