Remains backward compatible.
When encountering non-fatal errors SensorsTemperatures() returns the
temperatures for all the sensor we could read successfully. In that
case the custom error contains a list of all the non-fatal errors
encountered.
Example usage:
_, err := SensorsTemperatures()
if err != nil {
warns, ok := err.(*Warnings)
if ok {
fmt.Printf("%v\n", err)
for i, w := range warns.List {
fmt.Printf("Warning %v: %v\n", i+1, w)
}
} else {
t.Errorf("%v", err)
}
}
