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 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:
