# kdk\_get\_diskinfo(3)

获取指定磁盘的磁盘信息

## 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;
