[En-Nut-Discussion] Semaphores

[Marek Pavlu]

Hi Harald,

I often use semaphores from Nut/OS but I have several comment to safety.
NutSemPost and NutSemWait both write to same variable two byte variable with
enabled interupt!
My mofification guarantee correct activity and allow semaphores
(NutSemPostAsync) in blok with disabled interrupt or calling from
interrupt...


Regards,
