Function for sharing buffers to other indicators/experts

Hi, I need a function to share indicator buffers, so that they can easily retrieved by other indicators or experts in real time (on the same platform).
I want to avoid using the iCustom function. My goal is to change the parameters only in the source indicator and distribute the changed buffer values automatically to all linked indicators.

An idea is described in this article: https://www.mql5.com/en/articles/19

Unfortunately, this solution only works for 32-bit-systems (at least the dll). The job would be transferring this solution to work on 64-bit, but other solutions are also welcomed.

Thanks, Oliver
