I'm writing a software for the Linux environment. I'll need to share data between a daemon and a program running on the user's context.

I chose to use shared memory because it's faster.

I'm trying to use boost::interprocess::shared_memory_object but I'm facing a problem:

When I access the shared memory in my test case running in the same user context, everything works fine.

But when I access it using a program running in the current user when the shared memory was created as root, I get an access denied error.

I searched in the documentation for a way to enable access to all users but I found nothing.

Is there a way to do it?

Thanks in advance.

Silvio.
