IO::Seekable

Intended to be inherited by other IO::Handle-based objects to provide methods that allow you to seek the file descriptors. Has no constructor.

use IO::Seekable; package IO::XXX; @ISA = qw(IO::Seekable);

Provides two methods.

$fh->seek(offset, whence) 

Frontend for the corresponding built-in seek function, which sets a filehandle's position in the file. Takes the following arguments:

• offset
• The offset where you want to set the position.
• whence
• The position in the file that the offset is relative to. Possible values are: for the beginning of the file, for the current position, or for end of file. May also be expressed as the following constants, which are exported:
  • SEEK_SET
  • Beginning of file
  • SEEK_CUR
  • Current position
  • SEEK_END
  • End of file

$fh->tell( ) 

Frontend for the corresponding built-in tell function, which returns the current file position in bytes (starting from 0).
