NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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	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
