Documentation for Wire.requestFrom incorrect. The function returns a value.

[nickgammon]

The documentation for Wire.requestFrom states that the function returns "none", as documented here:

http://arduino.cc/en/Reference/WireRequestFrom

However in fact it returns the number of bytes obtained from the slave:

uint8_t TwoWire::requestFrom(uint8_t address, uint8_t quantity, uint8_t sendStop)

Please correct the web page to avoid further confusion.

The page was amended to read:

Returns

int : the number of bytes returned from the slave device

However it returns an unsigned 8-bit integer, that is, uint8_t (usually called the "byte" type).

Thank for the clarification, I was running and gunning when I updated that page.
