# kdk\_net\_freeall(3)

用于回收字符串列表

## NAME

kdk\_net\_freeall - 用于回收字符串列表

## SYNOPSIS

```
#include <libkync.h>

extern inline void kdk_net_freeall(char **ptr);

Link with -lkyhw.
```

## Detailed Description

The main function of the interface is to recycle a list of strings of type char \*\*;

The argument *ptr* is a list of strings of type char \*\*.

## RETURN VALUE

No return value
