IO::InnerFile(3)	       User Contributed Perl Documentation		 IO::InnerFile(3)

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
	   Instance methods.  Get/set the virtual length of the inner file.

       set_start START
       get_start
       add_start NBYTES
	   Instance methods.  Get/set the virtual start position of the inner file.

       binmode
       close
       flush
       getc
       getline
       print LIST
       printf LIST
       read BUF, NBYTES
       readline
       seek OFFFSET, WHENCE
       tell
       write ARGS...
	   Instance methods.  Standard filehandle methods.
