I'm currently working on an extension library for TCP/IP sockets.

I still got a functional API for simple single threaded connections or iterative servers,
but I want to support select() with Squirrel threads (coroutines).

There I have problems to understand native context switching with sq_suspendvm() and sq_wakeupvm().
I want to start any client-threads and the listener-thread suspended an use the select() to wakeup
threads getting data with sq_wakeupvm.
(I use a map of socket fd to HSQUIRRELVM to be able to wakeup threads that got data and resume them after
data processing).

My question is:

what is expected on the stack for each VM and what cleanup is needed when suspending.
Currently I just pass the stored VM to wakeup and do not expecting any result passing
by calling just:

sq_wakeupvm(threadVM, SQFalse, SQFalse, SQFalse, SQFalse);

Check this one to know the basics of socket programming...

you really should have a look at the source code of squirrel instead of making assumptions (sorry to say that).

sq_suspendvm for example effectively does NOTHING relevant.
suspend and resume are meant to build generators and are not suitable to support "true" multitasking at all.
Squirrel VMs are definitely NOT CAPABLE to run in a multithreaded way.

You need a different, non-multithreaded approach. (It's doable though - already done that :P)
