KDK_NC_GET_PHYMAC(3)       Library Functions Manual       KDK_NC_GET_PHYMAC(3)

NAME
       kdk_nc_get_phymac - <?><?><?><?><?><?><?><?><?>MAC<?><?>

SYNOPSIS
       #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.

       #include "libkync.h"
