This page just documents the differences from the C API and gives some examples. If you are not familiar with using libguestfs, you also need to read \fBguestfs\fR\|(3). .SS "IMPORTING THE MODULE" .IX Subsection "IMPORTING THE MODULE" The module is called \f(CW\*(C`guestfs\*(C'\fR. The full package name to import is \f(CW\*(C`libguestfs.org/guestfs\*(C'\fR. .SS "CREATING AND CLOSING THE HANDLE" .IX Subsection "CREATING AND CLOSING THE HANDLE" Use either \f(CW\*(C`guestfs.Create\*(C'\fR or \f(CW\*(C`guestfs.Create_flags\*(C'\fR to create the handle. The handle is closed implicitly if it is garbage collected. However it is probably a good idea to close it explicitly, either by calling \f(CW\*(C`g.Close\ ()\*(C'\fR or by deferring the same. .SS エラー .IX Subsection "エラー" \&\f(CW\*(C`guestfs.Create\*(C'\fR and \f(CW\*(C`guestfs.Create_flags\*(C'\fR return a simple \f(CW*error\fR, which is really just a C \f(CW\*(C`errno\*(C'\fR wrapped up in the appropriate golang struct. .PP All other calls return a \f(CW*GuestfsError\fR which (if non-nil) is a richer struct that contains the error string from libguestfs, the errno (if available) and the operation which failed. This can also be converted to a string for display. .SS LIMITATIONS .IX Subsection "LIMITATIONS" .IP \(bu 4 No support for events (see "EVENTS" in \fBguestfs\fR\|(3)). .IP \(bu 4 UUIDs are not returned in structures. .SH "例 1: ディスクイメージの作成" .IX Header "例 1: ディスクイメージの作成" \&\f(CW@EXAMPLE1\fR@ .SH "例 2: 仮想マシンのディスクイメージの検査" .IX Header "例 2: 仮想マシンのディスクイメージの検査" \&\f(CW@EXAMPLE2\fR@ .SH 関連項目 .IX Header "関連項目" \&\fBguestfs\fR\|(3), \fBguestfs\-examples\fR\|(3), \fBguestfs\-erlang\fR\|(3), \fBguestfs\-gobject\fR\|(3), \fBguestfs\-java\fR\|(3), \fBguestfs\-lua\fR\|(3), \fBguestfs\-ocaml\fR\|(3), \fBguestfs\-perl\fR\|(3), \fBguestfs\-python\fR\|(3), \fBguestfs\-recipes\fR\|(1), \fBguestfs\-ruby\fR\|(3), http://www.golang.org/, http://libguestfs.org/. .SH 著者 .IX Header "著者" Richard W.M.
