Usage
#include <libknet.h>
int knet_host_get_status(
knet_handle_t knet_h,
knet_node_id_t host_id,
struct knet_host_status *status
);
Overview
knet_host_get_status
knet_h - pointer to knet_handle_t
host_id - see knet_host_add(3)
status - pointer to knet_host_status struct
Structures
status of a knet host, returned from knet_host_get_status()
struct knet_host_status {
uint8_t reachable; /* Whether the host is currently reachable */
/*
* Whether the host is a remote node (not currently implemented)
*/
uint8_t remote;
/*
* Whether the host is external (not currently implemented)
*/
uint8_t external;
};
Return value
knet_handle_pmtud_get returns 0 on success -1 on error and errno is set.
