      Node.js N-API napi_get_cb_info

      新增于: v8.0.0 N-API version: 1 napi_status napi_get_cb_info(napi_env env, napi_callback_info cbinfo, size_t* argc, napi_value* argv, napi_value* thisArg, void** data) [in] env: The environment that the API is invoked under. [in] cbinfo: The callback info passed into the callback function. [in-out] argc: Specifies the size of the provided argv array and receives the actual count of arguments. [out] argv: Buffer to which the napi_value representing the arguments are copied. If there are more arguments than the provided count, only the requested number of arguments are copied. If there are fewer arguments provided than claimed, the rest of argv is filled with napi_value values that represent undefined. [out] this: Receives the JavaScript this argument for the call. [out] data: Receives the data pointer for the callback. Returns napi_ok if the API succeeded.

      This method is used within a callback function to retrieve details about the call like the arguments and the this pointer from a given callback info.
