Mark OTA valid

I am wondering what lib to use....

Esp_ota_mark_app_valid_cancel_rollback() in my sketch is not defined.

I am building off the basicOTA sketch. Kind of testing functions and stuff. I'll post code once I get home.

ESP support speaks of function but not where it's defined.

esp8266 Arduino boards package ArduinoOTA library?

I misspelled it. I'll try again
