KDK_NC_GET_IPV6(3)         Library Functions Manual         KDK_NC_GET_IPV6(3)

NAME
       kdk_nc_get_ipv6 - <?><?><?><?><?><?><?><?><?>IPv6<?><?>

SYNOPSIS
       #include <libkync.h>

       extern char** kdk_nc_get_ipv6(const char* nc);

       Link with -lkyhw.

Detailed Description
       The main function of the interface is to obtain all IPv6 addresses of
       the specified NIC nc

       The argument nc is the name of the NIC, such as "eno1".

RETURN VALUE
       On success, returns a list of IPv6 addresses, ending with NULL ,
       generated by alloc and required to be recycled by kdk_nc_freeall

       On error, return NULL.

EXAMPLES
       #include "libkync.h"
       #include <stdio.h>
       #include <stdlib.h>
