SYNOPSIS

ABSTRACT

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

DESCRIPTION

       Since this module tries to stick very closely to the C API, the documentation found at

	 L<http://developer.gnome.org/doc/API/2.0/gnome-vfs-2.0/>

       is the canonical reference.

       In addition to that, there's also the automatically generated API documentation: Gnome2::VFS::index.

       The mapping described in Gtk2::api also applies to this module.

       To discuss this module, ask questions and flame/praise the authors, join gtk-perl-list@gnome.org at lists.gnome.org.

KNOWN BUGS

       There are some memory leaks especially with respect to callbacks.  This mainly affects GnomeVFSAsync as well as some parts of GnomeVFSXfer
       and GnomeVFSOps.  GnomeVFSMime leaks some list data.

       GnomeVFSAsync is also known to crash under certain conditions when there are many concurrent transfers.

SEE ALSO

       Gnome2::VFS::index, Glib, Gtk2, Gtk2::api.
