The Interface Generator Application (IG) makes it easy to communicate between Erlang and C/C++ programs.
IG provides an easy way of making C functions accessible from Erlang and vice versa. The underlying communication can optionally be be based upon sockets or the
open_port/2BIF mechanism.
The Interface Generator will not be supported from next release of Erlang/OTP. Please, avoid to use it; use the application IC instead.
