kdk_nc_get_phymac(3)

kdk_nc_get_phymac3

获取指定网卡的物理mac地址

Usage

#include <libkync.h>

extern char* kdk_nc_get_phymac(const char *nc);

Link with -lkyhw.

Detailed Description

The main function of the interface is to obtain the physical MAC address of the specified NIC nc

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

Return value

On success, returns a physical MAC address of type char*, generated by alloc , which should be free ; If the specified NIC does not exist, NULL is returned.

On error, return NULL.
