The support for VxWorks is deprecated as of OTP 22, and will be removed in OTP 23.

The old legacy erl_interface library (functions with prefix erl_) is deprecated as of OTP 22, and will be removed in OTP 23. This does not apply to the ei library. Reasonably new gcc compilers will issue deprecation warnings. In order to disable these warnings, define the macro EI_NO_DEPR_WARN.

By default, the ei library is only guaranteed to be compatible with other Erlang/OTP components from the same release as the ei library itself. See the documentation of the ei_set_compat_rel() function on how to communicate with Erlang/OTP components from earlier releases.
