[Contiki-developers] Protothread semaphores

[milos r. <ro1...@gm...>]

Greetings,

I have a problem understanding the example on this page:
http://dias.cs.st-andrews.ac.uk/Contiki-related/examples/example.c

<http://dias.cs.st-andrews.ac.uk/Contiki-related/examples/example.c>PT_SEM_WAIT(pt,
&full) should block producer thread when the buffer is full. PT_SEM_WAIT()
blocks the thread when the counter iz zero. Where and how the counter *full
*is being decremented? I need an explanation of this example in more
details, please.

Thanks in advance!!!
