NAME

       nbd_connect_socket - connect directly to a connected socket

SYNOPSIS

        #include <libnbd.h>

        int nbd_connect_socket (
              struct nbd_handle *h, int sock
            );

DESCRIPTION

       Pass a connected socket "sock" through which libnbd will talk to the NBD server.

       The caller is responsible for creating and connecting this socket by some method, before
       passing it to libnbd.

       If this call returns without error then socket ownership is passed to libnbd.  Libnbd will
       close the socket when the handle is closed.  The caller must not use the socket in any
       way.

       This call returns when the connection has been made.  By default, this proceeds all the
       way to transmission phase, but nbd_set_opt_mode(3) can be used for manual control over
       option negotiation performed before transmission phase.

RETURN VALUE

       If the call is successful the function returns 0.

ERRORS

       On error "-1" is returned.

       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

       The following parameters must not be NULL: "h".  For more information see "Non-NULL
       parameters" in libnbd(3).

HANDLE STATE

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

VERSION

       This function first appeared in libnbd 1.2.

       If you need to test if this function is available at compile time check if the following
       macro is defined:

        #define LIBNBD_HAVE_NBD_CONNECT_SOCKET 1
