then in your main example below do a shmem_long_fadd on my_dso_val. It won’t work unless you’ve put smarts in the shmem library to go through the segments of loaded shared libraries and register them with the same mechanism used for the data segment of the executable.
In this case the "smart" part will be pretty complex.
