NAME

       nbd_connect_tcp - connect to NBD server over a TCP port

SYNOPSIS

        #include <libnbd.h>

        int nbd_connect_tcp (
              struct nbd_handle *h, const char *hostname,
              const char *port
            );

DESCRIPTION

       Connect (synchronously) to the NBD server listening on "hostname:port".  The "port" may be
       a port name such as "nbd", or it may be a port number as a string such as "10809".

       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", "hostname", "port".  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 1.0.

       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_TCP 1
