[erlang-questions] erlang:process_info/2

[Vlad Dumitrescu]

Hi all,

The documentation of this function lists the possible information items to
be retrieved and then states:

Note however, that not all implementations support every one of the above
Items.
My questions are:

* What happens if an item is not supported?
* What is meant by "implementation" here?
* Which implementations support what items?

best regards,
Vlad
