guestfs-golang - How to use libguestfs from Go

書式
 import "libguestfs.org/guestfs"

 g, errno := guestfs.Create ()
 if errno != nil {
     panic (fmt.Sprintf ("could not create handle: %s", errno))
 }
 defer g.Close ()
 if err := g.Add_drive ("test.img"); err != nil {
     panic (err)
 }
 if err := g.Launch (); err != nil {
     panic (err)
 }
 if err := g.Shutdown (); err != nil {
     panic (err)
 }

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 guestfs(3).

  IMPORTING THE MODULE
The module is called "guestfs". The full package name to import is "libguestfs.org/guestfs".

  CREATING AND CLOSING THE HANDLE
Use either "guestfs.Create" or "guestfs.Create_flags" 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 "g.Close ()" or by deferring the same.

  エラー
"guestfs.Create" and "guestfs.Create_flags" return a simple *error, which is really just a C "errno" wrapped up in the appropriate golang struct.

All other calls return a *GuestfsError 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.

  LIMITATIONS

•   No support for events (see "EVENTS" in guestfs(3)).

•   UUIDs are not returned in structures.
