The L specifies that the number is a long type, so -1L is a long set to negative one, and 1L is a long set to positive one. As for why ftell doesn’t just return NULL , it’s because NULL is used for pointers, and here a long is returned. Note that 0 isn’t used because 0 is a valid value for ftell to return.

## Is Ol high or low resistance?

Is “OL” a good reading on a multimeter? If the meter reads “OL”, the voltage you’re measuring is too high [3]. If you’re measuring low resistance, it’s possible that the meter will show “OL” because there is no way to display an absurdly high number. In this case, “0” is the better measurement to look for.

## Does Ol mean no resistance?

Resistance Testing

If the screen shows one or OL, it means that the device you are measuring has no continuity, i.e. somewhere there is an electrical signal that sends a multimeter broken and the resistance is infinite.

## What is 1L in Java?

(long) 1 is a constant expression (because the 1 is directly known) and hence, by the rules of the Java Language Specification (JLS), will be a long after compilation already. However, in my experience, it is far more common that people use the long literal and write 1L for readability.
