The hash +normally contains a single element: + + { + _g => [private data used by libguestfs] + } + +Callers can add other elements to this hash to store data for their own +purposes. The data lasts for the lifetime of the handle. + +Any fields whose names begin with an underscore are reserved +for private use by libguestfs. We may add more in future. + +It is recommended that callers prefix the name of their field(s) +with some unique string, to avoid conflicts with other users. + =head1 COPYRIGHT Copyright (C) %s Red Hat Inc. -- 1.8.3.1
