Stops reading if one of the callbacks returns NL_STOP or nl_recv returns either 0 or a negative error code. A non-blocking sockets causes the function to return immediately if no data is available. See nl_recvmsgs_report(). Positional arguments: sk -- Netlink socket (nl_sock class instance). cb -- set of callbacks to control behaviour (nl_cb class instance). Returns: 0 on success or a negative error code from nl_recv(). """
