KDK_NC_IS_UP(3)

NAME
kdk_nc_is_up - 检测指定网卡是否处于UP状态

SYNOPSIS
#include <libkync.h>

extern int kdk_nc_is_up(const char *nc);

Link with -lkyhw.

Detailed Description
The main function of the interface is to detect whether the specified NIC nc is in the UP state.

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

RETURN VALUE
On success, the Up status returns 1 and the Down status returns 0.

On error, return -1.
