## Detailed Description

This library contains network information.

## DATA STRUCTURES

Structure **route** contains information related to a Firewall:

**typedef struct route {**\
\
 	**char name\[32\]; //网卡名**\
     **char addr\[16\]; //网关地址**\
     **struct route \*next;**\
 **} routeMapList, \*prouteMapList;**

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

Structure **chain** contains information related to a Gateway:

**typedef struct chain {**\
\
 	**char total\[16\]; //链名**\
     **char policy\[32\]; //链的规则**\
     **pChainData data;**\
     **struct chain \*next;**\
 **} Chain, \*pChain;**

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

Structure **chain\_data** contains information related to a Gateway specific information:

**typedef struct chain\_data {**\
\
 	**char target\[8\];** \
     **char prot\[4 + 1\];**\
     **char opt\[4 + 1\];**\
     **char source\[32\];**\
     **char destination\[64\];**\
     **char option\[128\];**\
     **struct chain\_data \*next;**\
 **} chainData, \*pChainData;**

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

## RETURN VALUE

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