Article on Using RArray and RPointerArray on Symbians website

Paul.Todd | 09 May, 2008 00:03

I had an article published last week on Symbian's website.

This covers some of the more advanced use cases and constructs when using RArray and RPointerArray as well as some of the issues and common problems developers encounter using these powerful and useful classes.

Note that  the link points directly to a PDF!

http://developer.symbian.com/main/downloads/papers/advanced_RArray.pdf

One section that I did get to include was doing high performance IPC array marshalling which I will cover at some point in th future, primarily because I was over the allocated word limit and the code was quite complex due to the way I had to setup the demo to do it.

Great info!

I haven't used passing RArray over IPC. The described mechanisms seems quite complex (in chapter "Passing RArrays across processes with IPC").

Of course one could have another IPC call to figure out number of items, but even then there would have to be retry mechanism, if there are added items between calls. I guess this was the reason to do it this way?
