Re: [ST-users] coexist with pthread

[<ge...@co...>]

General answer is "state-threads can't coexist with pthreads". Note that there is no such thing as "generic pthreads". POSIX threads is just an API and the implementation is platform-dependent. For example, on Linux 2.4.* threads are kernel entities and on FreeBSD 4.* pthreads are implemented in user-land (libc_r threads are very similar to state-threads so there is no reason whatsoever to combine them).
So the real question is: why would you want to combine different thread models in a single app?
