NAME

kdk_net_get_netmask - 释放由kdk_net_get_iptable_rules返回的防火墙信息结构体

SYNOPSIS

#include <libkynetinfo.h>

extern void kdk_net_get_netmask(IN const char *nc, OUT char *mask);

Link with -lkynetinfo.

Detailed Description

The main function of the interface is to obtain subnet mask information.

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

The argument mask is the subnet mask information.

RETURN VALUE

No return value
