The ei and erl_interface are C interface libraries for communication with Erlang.

By default, the ei and erl_interface libraries are only guaranteed to be compatible with other Erlang/OTP components from the same release as the libraries themself. See the documentation of the ei_set_compat_rel() and erl_set_compat_rel() functions on how to communicate with Erlang/OTP components from earlier releases.
