## Detailed Description

This library contains disk information.

## DATA STRUCTURES

Structure **kdk\_diskinfo** contains information related to a disk:

**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;**

There are other members not documented here, which are only meant for libkydiskinfo internal use.

## RETURN VALUE

The return value is generally specific to the individual function called.

## CONFORMING TO

These functions are as per the withdrawn POSIX.1e draft specification. The following functions are Linux extensions: **kdk\_get\_disklist**(), **kdk\_get\_diskinfo**(), **kdk\_get\_hard\_disk**(), and **kdk\_get\_hard\_disk\_size**().
