[Interest] How to know QSharedMemory maximum system allowed size

[Calogero Mauceri]

Hi all,

I'm using QSharedMemory to share data between different processes.
I found out that there is a limit to the maximum size a shared memory 
segment can be. On Mac OS for example the QSharedMemory::create returned 
an error like "system-imposed size restrictions".
Is there a way programmatically to know which is the maximum size the 
system allows for the QSharedMemory, in order to adopt proper data 
splitting policies depending on it?

Thank you very much for your help.
