## Detailed Description

This library contains instantaneous information about the current system.

## DATA STRUCTURES

Structure **version\_t** contains information related to a system version number and patch version number information:

**typedef struct {**\
\
 	**char    \*os\_version;            //系统版本**\
     **char    \*update\_version;        //补丁版本**\
 **} version\_t;**

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

Structure **KPci** contains information related to a pci bus information:

**struct KPci {**\
\
 	**char slot\_path\[16\];**\
     **char class\_name\[128\];**\
     **char product\_name\[128\];**\
     **unsigned char rev;**\
     **char ss\_name\[256\];**\
     **char driver\_use\[1024\];**\
     **char \*\*modules;**\
     **int module\_count;**\
     **struct KPci \*next;**\
 **};**

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