获取远程服务端连接数 - GetRemoteServerConnCount ​

函数简介 ​

在 B 端 查询当前远程调度服务上的活跃连接数。

接口名称 ​

GetRemoteServerConnCount

DLL调用 ​

c
int32_t GetRemoteServerConnCount(int64_t instance, int64_t serverHandle);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug 对象指针，由 CreateCOLAPlugInterFace 接口生成。
serverHandle长整数型服务句柄，由 启动远程调度服务 - StartRemoteServer 或 启动共享内存远程调度服务 - StartRemoteServerShm 返回。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.GetRemoteServerConnCount(0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.GetRemoteServerConnCount(0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.GetRemoteServerConnCount(0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.GetRemoteServerConnCount(0);
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.GetRemoteServerConnCount(0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.GetRemoteServerConnCount(0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.GetRemoteServerConnCount(0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.GetRemoteServerConnCount(0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.GetRemoteServerConnCount(0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.GetRemoteServerConnCount(0);

原生 DLL 调用 ​

cpp
GetRemoteServerConnCount(instance, 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetRemoteServerConnCount(long ola, int serverHandle);

GetRemoteServerConnCount(instance, 0);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
ola.GetRemoteServerConnCount(instance, 0)

返回值 ​

当前连接数；-1 表示服务句柄无效。

注意事项 ​

  • 仅 B 端在已启动服务后调用。
