Hi, Is there any option to automatically increase the size of the 'Shared Memory' dynamically, in the shared memory objects of Interprocess library?

Thanks & Regards, Srinivas Gardas

Automatically no. That would be nearly impossible to achieve because every process attached to the segment would need to be notified, all of them should remap it, and be successful. And all those steps should be atomically executed. The only option to grow shared memory/memory mapped files is to make sure no processes are attached to it and call "managed_shared_memory::grow()". You can minimize the size of the shared memory/memory mapped file (when no process is using it) calling "shrink_to_fit". Something like: //Warning: no process should be using this shared memory //Increase shared memory size with extra 16K managed_shared_memory::grow("shmem_name", 16*1024); //Minimize the size of the shared memory managed_shared_memory::shrink_to_fit("shmem_name"); //Now open it again with the new size managed_shared_memory shm(open_only, "shmem"); These functions are experimental and they are not explained in the docs. I will add them as official when I'm sure they are production ready. If you want to test them and report if they are useful and correct, I would be glad. Regards, Ion
