# IO::Seekable(3pm)

supply seek based methods for I/O objects

## 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 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
```
