write() returning
byte : the number of bytes written. It is not necessary to read this.
https://www.arduino.cc/en/Reference/WiFiClientWrite

however V2.2.0 ESP8266WiFi ClientContext.h write() returns

Code: Select all            return will_send - _size_sent;

were as it should return

Code: Select all            return size_sent;

to be consistent with Arduino docs, and with usual C definition of write()
OR could return

Code: Select all           return  will_send;

since

Code: Select all           _size_sent = will_send;

is set a few lines above
