Threads and f-stack

[RainM]

Hello,

I'm trying to port our network application from kernel's epoll to fstack's implementation.
I compiled hello world application from f-stack sources and it works perfectly. Next step, I incorporated appropriate f-stack's calls to my code (instead of kernel's epoll/socket/...). Here I call ff_init + ff_run in one place but I can't place my logic to ff_run callback. I tried to add sleeps to ff_run's loop and poll f-stack's sockets from another thread (I see ff_pthread_create and set TLS current thread value to my thread) - but it doesn't work. I get no data from f-socket's epoll called in my thread. What I do wrong way? Is it possible to read epoll data from another single thread (f-stack's thread which run ff_run callback will just sleep in this case and my thread will be single reader from sockets)?

Speaking more general way, what is the threading model for F-Stack? I see notes about ff_* functions to be called from business logic threads and these threads are separated from stack's ones. But what ff_pthread_create function does? Why it just copy current thread pointer to TLS variable? Why not just use static variable? If F-Stack is a single-threaded application/stack, is it possible to provide existing thread to f-stack?
