tell
tell filehandle
Returns the current file position (in bytes,
0-based) for
filehandle. This value is typically fed
to the seek function at a
future time to get back to the current position. If
filehandle is omitted, the function
returns the position of the last file read. File positions are
only meaningful on regular files. Devices, pipes, and sockets have
no file position.
