NAME

       knet_link_get_status - Get the status (and statistics) for a link.

SYNOPSIS

       #include <libknet.h>

       int knet_link_get_status(
           knet_handle_t             knet_h,
           knet_node_id_t            host_id,
           uint8_t                   link_id,
           struct knet_link_status  *status,
           size_t                    struct_size
       );

DESCRIPTION

       knet_link_get_status

       knet_h - pointer to knet_handle_t

       host_id - see knet_host_add(3)

       link_id - see knet_link_set_config(3)

       status - pointer to knet_link_status struct

       struct_size  -  max  size  of  knet_link_status - allows library to add fields without ABI
       change. Returned structure will be truncated to this length and .size member indicates the
       full size.

              struct status {
                  size_t             size;
                  char               src_ipaddr[KNET_MAX_HOST_LEN];
                  char               src_port[KNET_MAX_PORT_LEN];
                  char               dst_ipaddr[KNET_MAX_HOST_LEN];
                  char               dst_port[KNET_MAX_PORT_LEN];
                  uint8_t            enabled;
                  uint8_t            connected;
                  uint8_t            dynconnected;
                  unsigned long long latency;
                  struct timespec    pong_last;
                  unsigned int       mtu;
                  unsigned int       proto_overhead;
                  struct             stats;
              };

RETURN VALUE

       knet_link_get_status returns 0 on success -1 on error and errno is set.
