1 To test a plugin using libguestfs
2 =================================
8 test_start_nbdkit ("plugin", <plugin args ...>, NULL)
10 at the beginning. This starts the nbdkit server.
12 - Open a libguestfs handle, and configure the NBD client using:
14 guestfs_add_drive_opts (g, "",
15 GUESTFS_ADD_DRIVE_OPTS_FORMAT, "raw",
16 GUESTFS_ADD_DRIVE_OPTS_PROTOCOL, "nbd",
17 GUESTFS_ADD_DRIVE_OPTS_SERVER, server,
20 'server' is a global that is initialized by 'test_start_nbdkit' and
21 points to the nbdkit server socket.
23 - Perform tests via libguestfs using the libguestfs device "/dev/sda",
24 which corresponds to the NBD drive exposed by the plugin.
26 - Close the handle and exit. An 'atexit' handler installed by
27 'test_start_nbdkit' cleans up the server automatically.
29 For an example, see 'test-data.c'.
31 To test a plugin using libnbd
32 =============================
34 - Open a libnbd handle, and configure it using:
36 char *args[] = { "nbdkit", "-s", "--exit-with-parent",
37 "plugin", <plugin args ...>, NULL };
38 nbd_connect_command (nbd, args);
40 - Perform tests via libnbd.
42 For an example, see 'test-delay.c'.
