This shows how to use shared memory in a DLL with Delphi 32bit. Accessing shared memory objects via the filesystem On Linux, shared memory objects are created in a (tmpfs(5)) virtual filesystem, normally mounted under /dev/shm. Windows platform will generally ignore the hint. VIRT stands for the virtual size of a process, which is the sum of memory it is actually using, memory it has mapped into itself (for instance the video card's RAM for the X server), files on disk that have been mapped into it (most notably shared libraries), and memory shared with other processes. It is an attractive solution for users who require the GPU’s full potential during brief periods. I used Posix shared memory to communicate between 2 process. If a client container requests a block larger than a certain threshold size, then the pool is bypassed, and the allocate/deallocate request is passed to ::operator new directly. Log in as root.
