[erlang-questions] What is the best way to parse complex erlang terms in port drivers?
Thu Jun 7 10:04:39 CEST 2012
Thanks a lot.
I have understood that in case of eterms it will be necessary to traverse the parsed structure somehow to transform it into the target c-structure, so ei interface seems more natural to use as I will be creating the c-structure during parsing.

It seems like the eterm interface is the older/slower interface, and the ei interface is the newer/faster interface (where you have better control over memory usage). That is just based on experience, and is unlikely to be found in the documentation.
