NAME

6       knet_host_enable_status_change_notify  - Install a callback to get host
7       status change events.

SYNOPSIS

10       #include <libknet.h>
11
12       int knet_host_enable_status_change_notify(
13           knet_handle_t  knet_h,
14           void          *host_status_change_notify_fn_private_data,
15           void(*)(void *private_data, knet_node_id_t host_id, uint8_t reachable, uint8_t remote, uint8_t external)  host_status_change_notify_fn
16       );

DESCRIPTION

19       knet_host_enable_status_change_notify
20
21       knet_h - pointer to knet_handle_t
22
23       host_status_change_notify_fn_private_data - void pointer to  data  that
24       can be used to identify the callback
25
26       host_status_change_notify_fn  -  is a callback function that is invoked
27       every time there is a change in the host status. host status is identi‐
28       fied by:
29
30       reachable, this host can send/receive data to/from host_id
31
32       remote,  0 if the host_id is connected locally or 1 if the there is one
33       or more knet host(s) in between. NOTE: re-switching  is  NOT  currently
34       implemented,  but  this  is  ready  for future and can avoid an API/ABI
35       breakage later on.
36
37       external, 0 if the host_id is configured locally or 1 if  it  has  been
38       added from remote nodes config. NOTE: dynamic topology is NOT currently
39       implemented, but this is ready for future  and  can  avoid  an  API/ABI
40       breakage  later  on.  This function MUST NEVER block or add substantial
41       delays.

RETURN VALUE

44       knet_host_status_change_notify returns 0 on success  -1  on  error  and
45       errno is set.
