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

<p>This module provides support for communication between distributed
Erlang nodes and C-nodes, in a manner that is transparent to Erlang
processes.</p>
