Erlang: How to get current file cursor position

In Erlang, the file module allows one to move the file cursor to a given position by file:position/2. But after performing an operation such as file:read_line/1, the cursor now moves.

Is there any way to get its current location?

Sorry if this seems silly, I'm new to Erlang and I cannot seem to find any relevant function in the module documentation to perform this. Any help will be much appreciated.

To get the current file position, call file:position/2 with the atom cur as the second argument.
