[erlang-questions] Why avoid calling enif_make_atom?
Thu Feb 23 12:04:23 CET 2017
All of the NIF-using Erlang projects I've found seem to allocate their
atoms during load. Some examples:
- jiffy: https://github.com/davisp/jiffy/blob/master/c_src/jiffy.c
- re2: https://github.com/tuncer/re2/blob/master/c_src/re2_nif.cpp#L180
I also found some skeleton NIF code, at
that checks enif_make_existing_atom first.
I guess my question is:
What's the harm in calling enif_make_atom whenever I need an atom
term? Does it leak atoms?
