# ftell

## Purpose

Get file position indicator.

## Synopsis

    position = ftell(fid)

## Description

`position = ftell(fid)` returns the location of the file position indicator in the specified file. `position` is indicated in bytes from the beginning of the file. `fid` is a integer file identifier obtained from `fopen`.

The value of position is a nonnegative integer if the query is successful. If -1 is returned, it indicates that the query was unsuccessful; use `ferror` to determine the nature of the error.
