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)".
