- IO::Seekable - supply seek based methods for I/O objects

- IO::Seekable does not have a constuctor of its own as is intended to be
- inherited by other IO::Handle based objects. It provides methods which
- allow seeking of the file descriptors.
-
- If the C functions _f_g_e_t_p_o_s() and _f_s_e_t_p_o_s() are available, then
- IO::File::getpos returns an opaque value that represents the current
- position of the IO::File, and IO::File::setpos uses that value to return
- to a previously visited position.
-
- See the _p_e_r_l_f_u_n_c manpage for complete descriptions of each of the
- following supported IO::Seekable methods, which are just front ends for
- the corresponding built-in functions:
-
- seek
- tell
