7

SYNOPSIS

9        #include <libnbd.h>
10
11        int nbd_connect_socket (struct nbd_handle *h, int sock);
12

DESCRIPTION

14       Pass a connected socket "sock" through which libnbd will talk to the
15       NBD server.
16
17       The caller is responsible for creating and connecting this socket by
18       some method, before passing it to libnbd.
19
20       If this call returns without error then socket ownership is passed to
21       libnbd.  Libnbd will close the socket when the handle is closed.  The
22       caller must not use the socket in any way.
23

RETURN VALUE

25       If the call is successful the function returns 0.
26

ERRORS

28       On error "-1" is returned.
29
30       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details
31       of the error.
32

HANDLE STATE

34       The handle must be newly created, otherwise this call will return an
35       error.
