Returns the current position in bytes for FILEHANDLE, or -1 on error. FILEHANDLE may be an expression whose value gives the name of the actual filehandle. If FILEHANDLE is omitted, assumes the file last read.
Note the in bytes: even if the filehandle has been set to
operate on characters (for example by using the
layer), tell will return byte offsets, not
character offsets (because that would render
tell rather slow).
