NAME

kdk_get_hard_model - 获取硬盘型号

SYNOPSIS

#include <libkydiskinfo.h>

extern char* kdk_get_hard_model(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 model information.

RETURN VALUE

On success, Returns the model of hard drive; The returned string needs to be released by free

On error, return NULL.
