.SH 説明
.IX Header "説明"
This manual page documents how to call libguestfs from the Go programming language.  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.
