ABSTRACT

76       This module allows you to interface with the GNOME Virtual File System
77       library.  It provides the means to transparently access files on all
78       kinds of filesystems.
79

DESCRIPTION

81       Since this module tries to stick very closely to the C API, the
82       documentation found at
83
84         L<http://developer.gnome.org/doc/API/2.0/gnome-vfs-2.0/>
85
86       is the canonical reference.
87
88       In addition to that, there's also the automatically generated API
89       documentation: Gnome2::VFS::index.
90
91       The mapping described in Gtk2::api also applies to this module.
92
93       To discuss this module, ask questions and flame/praise the authors,
94       join gtk-perl-list@gnome.org at lists.gnome.org.

KNOWN BUGS

97       There are some memory leaks especially with respect to callbacks.  This
98       mainly affects GnomeVFSAsync as well as some parts of GnomeVFSXfer and
99       GnomeVFSOps.  GnomeVFSMime leaks some list data.
100
101       GnomeVFSAsync is also known to crash under certain conditions when
102       there are many concurrent transfers.
103
