# kdk\_net\_get\_port\_stat(3)

获取指定网络端口的状态

## NAME

kdk\_net\_get\_port\_stat - 获取指定网络端口的状态

## SYNOPSIS

```
#include <libkynetinfo.h>

extern int kdk_net_get_port_stat(int port);

Link with -lkynetinfo.
```

## Detailed Description

The main function of the interface is to obtain the status of the specified network port.

The argument *port* is the port number.

## RETURN VALUE

On success, returns a port status of type int, such as TCP\_ESTABLISHED:0x1, TCP\_SYN\_SENT:0x2, TCP\_SYN\_RECV:0x3, TCP\_FIN\_WAIT1:0x4, TCP\_FIN\_WAIT2:0x5, TCP\_TIME\_WAIT:0x6, TCP\_CLOSE:0x7, TCP\_CLOSE\_WAIT:0x8, TCP\_LAST\_ACL:0x9, TCP\_LISTEN:0xa, TCP\_CLOSING:0xb.

On error, return **-1.**
