bson_as_json_with_opts()  encodes bson as a UTF-8 string in the MongoDBExtendedJSONformat or libbson'sLegacyExtendedJSON.

       The caller is responsible for freeing the resulting UTF-8 encoded string by calling bson_free() with  the
       result.

       If non-NULL, length will be set to the length of the result in bytes.

       The opts structure is used to pass options for the encoding process. Please refer to the documentation of
       bson_json_opts_t for more details.

          bson_t *b = BCON_NEW ("foo", BCON_INT32 (123));
          bson_json_opts_t *opts = bson_json_opts_new (BSON_JSON_MODE_CANONICAL, BSON_MAX_LEN_UNLIMITED);
          char *str = bson_as_json_with_opts (b, NULL, opts);
          printf ("Canonical Extended JSON: %s\n", str);
          // Prints:
          // Canonical Extended JSON: { "foo" : { "$numberInt" : "123" } }
          bson_free (str);
          bson_json_opts_destroy (opts);
          bson_destroy (b);

       • bson: A bson_t.

       • length: An optional location for the length of the resulting string.

       • opts: A bson_json_opts_t.

       If successful, a newly allocated UTF-8 encoded string and length is set.

       Upon failure, NULL is returned.
