Protothreads is a programming model invented by Adam Dunkels that combines the advantages of event-driven (sometimes also called state machine) programming and threaded programming. The main advantage of the event-driven model is efficiency, both speed and memory usage. The main advantage of the threaded model is algorithm clarity. Protothreads gives you both. A protothread is an extremely lightweight thread. As with event-driven programming, there is a single stack; but like threaded programming, a function can (at least conceptually) block. This protothreads implementation:
* is not an implementation of POSIX threads or any other standard API
* does not require assembly-language code or use setjmp/longjmp
* is independent of CPU architecture
* schedules threads non-preemptibly and deterministically.
* standard version does not take a
