Can QSharedMemory be assumed to stay in physical memory?

[A Former User]

Or, can I prevent shared memory from being paged out, so a pointer to the memory is constant? (Or is this the case anyway?)

Using mlock() for example?

Thanks,

The pointer is constant, independent of whether the os pages out the memory or not.

You can't assume it stays in physical memory (so: mlock it) -- that doesn't imply that the address of the shared segment changes.

Thank you for your helpful answers.
