IO::Seekable(3) Perl Programmers Reference Guide IO::Seekable(3)NAMEIO::Seekable - supply seek based methods for I/O objects
SYNOPSIS
use IO::Seekable;
package IO::Something;
@ISA = qw(IO::Seekable);
DESCRIPTIONIO::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
