ESP8266_Lib.h vs ESP8266WiFi.h (The difference between these 2 libraries)

Hello Juraj.

What I want to do is to establish a void wifi_connection_check(). Not, Blynk.connected() = true . Therefore, i need to find the bool which represents the wifi connection. Esp8266Wifi library contains the (wifi.status() != WL_CONNECTED) . But not in BlynkSimpleShieldEsp8266.h library.

Thanks.
