NAME

kdk_get_diskinfo - 获取指定磁盘的磁盘信息

SYNOPSIS

#include <libkydiskinfo.h>

extern kdk_diskinfo *kdk_get_diskinfo(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_disklist() function returns an element from a value to obtain disk information.

RETURN VALUE

kdk_diskinfo is a structure that stores disk information, as follows:

typedef struct _kdk_diskinfo{
char *name; // 绝对路径
char *vendor; // 制造商
char *model; // 型号
char *serial; // 序列号

kdk_disk_type disk_type; // 磁盘类型，固态 or 机械 or 混合
kdk_disk_interface_type inter_type; // 接口类型
unsigned int rpm; // 转速，注意固态是没有转速概念的

unsigned long long sectors_num; // 扇区数量
unsigned int sector_size; // 每个扇区的字节数
float total_size_MiB; // 磁盘容量，MiB为单位

unsigned int partition_nums; // 该磁盘/分区下的子分区数量
char *uuid; // UUID
short mounted; // 是否已挂载
char *mount_path; // 挂载路径
kdk_disk_format format; // 格式化类型
kdk_disk_partition_type part_type; // 分区类型
char *fwrev; //固件版本信息

}kdk_diskinfo;
