napi set instance data

napi_status napi_set_instance_data(napi_env env,
                                   void* data,
                                   napi_finalize finalize_cb,
                                   void* finalize_hint);

• [in] env: The environment that the N-API call is invoked under.
• [in] data: The data item to make available to bindings of this instance.
• [in] finalize_cb: The function to call when the environment is being torn down. The function receives data so that it might free it. [napi_finalize][] provides more details.
• [in] finalize_hint: Optional hint to pass to the finalize callback during collection.

Returns napi_ok if the API succeeded.

This API associates data with the currently running Agent. data can later be retrieved using napi_get_instance_data(). Any existing data associated with the currently running Agent which was set by means of a previous call to napi_set_instance_data() will be overwritten. If a finalize_cb was provided by the previous call, it will not be called.
