Question about bidrectional communication using shared maps

[kimdh98]

Hi, I have a question about how the shared maps work.
Is my understanding that a pair of linked maps only allow communication in one direction?
Referring to the example in the documentation about shared maps, if shared_map0 is linked to shared_map_output0, the element updates in shared_map0 will be reflected in shared_map_output0, but not the other way round.

If this is true, is there any way to make sure the sync go both ways, or is creating two pairs of "input maps" and "output maps" the only way?

Nevermind, it seems that I was updating the elements incorrectly.
I was following the *(uint32_t*)c = cnt; updates following the example_standalone.
But using jbpf_map_update_elem() works fine.
