AU Threading Question

Subject: AU Threading Question

Hi all,

By now I should know better about all this. However, I have a question about threading issues within an AU.

In the render thread of our AU instruments we calculate various peak meter level readings and store this data into a plain C float array. The array is a member of the AU class itself. In the Cocoa view an NSTimer fires off a GetProperty() event which performs a memcpy of the C array which the view uses to update the meters.

Is there some potential for blocking here if the Render thread is writing the peak data when the GetProperty() call comes in?

Or is it possible that the Render method will have to wait for the GetProperty()read to finish before writing new values?

Thanks for any help, Stephen _______________________________________________ Do not post admin requests to the list. They will be ignored.
