knet_link_get_config3
Get the link configutation information.
Usage
#include <libknet.h>
int knet_link_get_config(
knet_handle_t knet_h,
knet_node_id_t host_id,
uint8_t link_id,
uint8_t *transport,
struct sockaddr_storage *src_addr,
struct sockaddr_storage *dst_addr,
uint8_t *dynamic,
uint64_t *flags
);
Overview
knet_link_get_config
knet_h - pointer to knet_handle_t
host_id - see knet_host_add(3)
link_id - see knet_link_set_config(3)
transport - see knet_link_set_config(3)
src_addr - sockaddr_storage that can be either IPv4 or IPv6
dst_addr - sockaddr_storage that can be either IPv4 or IPv6
dynamic - 0 if dst_addr is static or 1 if dst_addr is dynamic. In case of 1, dst_addr can be NULL and it will be left untouched.
flags - KNET_LINK_FLAG_*
Return value
knet_link_get_config returns 0 on success. -1 on error and errno is set.
