Thread synchronization

[Giulio Petrucci]

Hi there,

I have two threads:
- thread A: write some data into a stream (audio on an audio card,...etc...)
- thread B: listen for an event (mouse click,...)
I need to stop A when the event B's listening to occures.

Please, could anyone help me?

Thanks in advance,
Giulio - Italia

Maybe i have misunderstood, but i presume an event fires that tells Thread B
to start? And you want Thread A to stop when thread B starts? So stop Thread
A when the event that triggers B to start fires? have i misunderstood you
here?

Also if they will not run simulatenously, why the need to run them on
separate threads in the first place?

Maybe. ;-)

Because they're using currently two different HW resources.

Bye,

Hi Bruce,

Have B's event listener set a boolean flag in the object that contains
the code for A. Then have A poll (test) the flag at regular intervals,
say before each write.

I see.
So the only way is to use a buffer for writing data.

Thanks for your suggestion!
