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

DISCLAIMER

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
