+/**
+ * \file api.h
+ * \brief hICN control library API
+ *
+ * This API supports basic hICN objects (face, route, punting) plus
+ * implementation-specific ones (connection, listener). Currently, this library
+ * only supports the hicn-light forwarder.
+ *
+ * For each object, a set of methods is provided among:
+ * - CREATE, GET, UPDATE, DELETE, LIST
+ * - CMP, PARSE, SNPRINTF
+ * - additionally, attribute getters and/or setters are provided and denoted
+ * GET( attribute ) and SET( attribute )
+ *
+ * A summary per-object is presented here:
+ *
+ * | CRE GET UPD DEL LST | VAL CMP PAR SNP | attributes [GET/SET]
+ * +------------+---------------------+-------------+---------------------------
+ * | face | O O ! O O | ! ! O | state [-S]
+ * | route | O - ! O O | ! O - |
+ * | punting | ! - ! ! ! | ! ! ! |
+ * +------------+---------------------+-----------------+---------------------------
+ * | cache | | | store [!!], serve [!!]
+ * | strategy | | |
+ * | FIB | | |
+ * | PIT | | |
+ * | WLDR | | |
+ * | MAP-Me | | |
+ * +------------+---------------------+-----------------+---------------------------
+ * | connection | O O ! O O | O O O | state [-S]
+ * | listener | O O ! - O | O O O O |
+ * +------------+---------------------+-----------------+---------------------------
+ *
+ * LEGEND: [O] implemented, [!] in progress / TODO, [-] not supported
+ *
+ * NOTES:
+ *
+ * - Different extensions of the forwarder functionalities bring both new API
+ * calls, and new object attributes. While it is expected that the former will
+ * only raised NACK answers because of unsupported API calls, the latter will
+ * certainly trigger incompatibilities. It is expected that the forwarder
+ * validates the message length and returns a NACK too. In that case, we
+ * provide a set of defines to preserve backwards compatibility. At the
+ * moment, those defines are :
