.TH "KDK_NET_GET_PORT_STAT" 3 "Thu Sep 14 2023" "Linux Programmer's Manual" \"
.SH NAME
kdk_net_get_port_stat - 获取指定网络端口的状态
.SH SYNOPSIS
.nf
.B #include <libkynetinfo.h>
.sp
.BI "extern int kdk_net_get_port_stat(int "port ");" 
.sp
Link with \fI\-lkynetinfo\fP.
.SH "Detailed Description"
The main function of the interface is to obtain the status of the specified network port.
.PP
The argument
.I port
is the port number.
.SH "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.
.PP
On error, return
.BR -1.
