KDK_NET_GET_RESOLV_CONF(3)

NAME
kdk_net_get_resolv_conf - 获取DNS配置文件

SYNOPSIS
#include <libkynetinfo.h>

extern char** kdk_net_get_resolv_conf();

Link with -lkynetinfo.

Detailed Description
The main function of the interface is to obtain the DNS configuration file.

RETURN VALUE
On success, returns the DNS configuration file of type char **, ending with a NULL character; Generated by alloc and needs to be recycled by kdk_net_freeall

On error, return NULL.
