KDK_GET_HARD_SERIAL(3)

NAME
kdk_get_hard_serial - 获取硬盘序列号

SYNOPSIS
#include <libkydiskinfo.h>

extern char* kdk_get_hard_serial(const char *diskname);

Link with -lkydiskinfo.

Detailed Description
Based on the specified disk name diskname, such as absolute path such as /dev/sda, or kdk_get_hard_disk() function returns an element in the value to obtain hard drive serial number information.

RETURN VALUE
On success, Returns the serial number of hard drive; The returned string needs to be released by free

On error, return NULL.
