Can I create multiple data-structures for single QSharedMemory

[rawfool]

I need to share multiple data-structures across from my QSharedMemory. I tried "Shared Memory" example, which loads a image from file & from shared memory.
I need to share multiple structures across QSharedMemory for non-Qt application. If not, is it possible to avoid reading a all the sharedmemory chunk every time when I poll for a change ? Is there any example available depicting this scenario ? Kindly help me. Thank you.
