ASN.1 to C compiler takes the ASN.1 module files (example) and generates the C++ compatible C source code. That code can be used to serialize the native C structures into compact and unambiguous BER/OER/PER/XER/JER-based data files, and deserialize the files back. However, this variant also supports automatic generation of Python C extensions.
