Erlang: How to get current file cursor position

Question

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.

要获取当前文件位置，请使用原子cur作为第二个参数调用file:position/2 。
