NAME

IO::InnerFile - define a file inside another file

SYNOPSIS

    ### Read a subset of a file:
    $inner = IO::InnerFile->new($fh, $start, $length);
    while (<$inner>) {
	...
    }

DESCRIPTION

If you have a filehandle that can seek() and tell(), then you can open an IO::InnerFile on a range of the underlying file.

PUBLIC INTERFACE

new FILEHANDLE, [START, [LENGTH]]

Class method, constructor. Create a new inner-file opened on the given FILEHANDLE, from bytes START to START+LENGTH. Both START and LENGTH default to 0; negative values are silently coerced to zero.

Note that FILEHANDLE must be able to seek() and tell(), in addition to whatever other methods you may desire for reading it.

set_length LENGTH

get_length

add_length NBYTES
