There is publicly available documentation
Arduino sources are open source. You can browse the sources.
Type in google "Arduino esp8266 source github" and you may find . From there you can ex. type WL_CONNECTED in search bar above and find this line of code:
typedef enum { WL_NO_SHIELD = 255, // for compatibility with WiFi Shield library WL_IDLE_STATUS = 0, WL_NO_SSID_AVAIL = 1, WL_SCAN_COMPLETED = 2, WL_CONNECTED = 3, WL_CONNECT_FAILED = 4, WL_CONNECTION_LOST = 5, WL_WRONG_PASSWORD = 6, WL_DISCONNECTED = 7 } wl_status_t;
