Does anyone know if it's possible to use Thread.GetCompr essedStack and Thread.SetCompr essedStack as the basis for a coroutine
library? There doesn't seem to be a lot of documentation on these methods, although I seem to remember reading somewhere that they
are intended for internal .Net use and aren't really supposed to be used by applications.
Thanks,
Ken

It may be possible, but the framework has a security attribute on it that I
was never able to bypass. I'm no master of security but it certainly isn't
terribly happy about it, meaning such a library would be *very* security
fragile. If it is possible it may well not be a feasiable tool to use
anywhere.
*HOWEVER*, I think it could be possible to achieve psuedo-coroutines(look
and act liek them without full stack swapping) using techniques like those
used in C# for its iterators and anonymous methods. That is, writing
acompiler that generates state machines and uses non-stack based locals. I'm
just not sure how well that will work in the real world.
Ken,
The documentation for these in .NET 2.0 no longer states that they are
for internal use only. As a matter of fact, I believe because of the work
that was done to host the runtime in SQL server, support for fibers as
managed threads was added in.
Now, whether or not the Thread class uses fibers, I think that in
general, you would have to host the runtime to set that particular setting.
I'm not sure of the specifics, but I would poke around in the beta, as I
know significant changes have been made to the Thread object.
Hope this helps.

It seems to me that in python, generators are not truly coroutines. I
do not understand why. What I see is that generators are used almost
exclusively for generation of lists just-in-time. Side effects are
frowned upon. Coroutines, in contrast, are like split functions where
side effects are often as important or more important than return
values. I am currently writing a real time strategy game where I have
visual effects and use...

State Machines and Coroutines
The other thread on goto: Lead me to want to ask... In the spirit of
state machines and coroutines, This n00b to C would like to know if
setjmp/longjmp are the only way to break out of a routine; leave the
function and re-enter the stack state.
I ask this because I've only briefly, as yet, reviewed these functions
and I believe longjmp will only return a designated int. Therefore I

I would really like to know more about python 2.5's new generator
characteristics that make them more powerful and analogous to
coroutines. Is it possible for instance to employ them in situations
where I would normally use a thread with a blocking I/O (or socket)
operation? If it is, could someone show me how it can be done? There
appears to be a very limited amount of documentation in this repect,
unfortunately.
Thank you.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
