RL-ARM Multiple initiations of Semaphore

Ã…ke Forslund

Hi,

I'm using the RT-lib and was wondering what happens if a semaphore is initiated multiple times during.

Does this reset the token-counter of the semaphore, or will it simply return without doing anything at all?

Is the semaphore registered somewhere when os_sem_init() is called that could mean memory leakage if it is initiated multiple times?

I'm thankful for any answers.

Best Regards

    Thanks for the answers,

    I think I now have a pretty good picture of what will work and what won't.

    I'm only using semaphores with no timeout but possible deadlocks are not to be taken lightly. If I proceed with this solution I will have to be really careful before re-initialization, I will have to think about this for a while...
