IO::Seekable(3)	 Perl Programmers Reference Guide IO::Seekable(3)

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

SYNOPSIS
	   use IO::Seekable;
	   package IO::Something;
	   @ISA = qw(IO::Seekable);

DESCRIPTION
       IO::Seekable does not have a constructor of its own as it
       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 fgetpos() and fsetpos() 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 perlfunc 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

       perlop manpage, the IO::Handle manpage the IO::File
       manpage
