IO::Seekable

See the current Perl documentation for IO::Seekable.

Here is our local, out-dated (pre-5.6) version:


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



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



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 perlfunc 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
