NAME

libnbd-golang - how to use libnbd from Go

SYNOPSIS

 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)

DESCRIPTION

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).

HANDLES

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.

ERRORS

Most calls return either a single LibnbdError or a pair (ret, LibnbdError).

EXAMPLES

This directory contains examples written in Go:
