17 Return true if this connection is ready to start another option
18 negotiation command while handshaking with the server. An option
19 command will move back to the connecting state (see
20 nbd_aio_is_connecting(3)). Note that this state cannot be reached
21 unless requested by nbd_set_opt_mode(3), and even then it only works
22 with newstyle servers; an oldstyle server will skip straight to
23 nbd_aio_is_ready(3).

26 This call returns a boolean value.

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