setNewDataSem

Technical C/C++

I assume the function setNewDataSem allows me to pass a handle to a semaphore that will get processed each time a data packet arrives.

I’d like to use this mechanism instead of polling to see if a new message has arrived. Is this semaphore given (semGive) or flushed (semFlush) each time?

It does not seem to work no matter how I use it.

Thanks

This actually does work. You can block any task on a semapahore you register this way. There is no need to give the semaphore back each time, it seems the semaphore gets flushed, not given, each time a new message comes in. So this is a great way to not have to poll to see if a new message has arrived.
