libnbd-golang - how to use libnbd from Go
import "libguestfs.org/libnbd"
h, err := libnbd.Create()
if err != nil {
panic(err)
}
defer h.Close()
uri := "nbd://localhost"
err = h.ConnectUri(uri)
if err != nil {
panic(err)
}
size, err := h.GetSize()
if err != nil {
panic(err)
}
fmt.Printf("size of %s = %d\n", uri, size)This manual page documents how to use libnbd to access Network Block Device (NBD) servers from the Go programming language. The Go bindings work very similarly to the C bindings so you should start by reading libnbd(3).
Create a libnbd handle of type Libnbd by calling Create().
You can either close the handle explicitly by a deferred call to h.Close() or it will be closed automatically when it is garbage collected.
Most calls return either a single LibnbdError or a pair (ret, LibnbdError).
