发送数据 - TcpClientSend ​

函数简介 ​

发送数据（异步操作）。

接口名称 ​

TcpClientSend

DLL调用 ​

c
int32_t TcpClientSend(int64_t instance, int64_t client_handle, int64_t data, int32_t data_len);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
client_handle长整数型客户端句柄
data长整数型数据指针
data_len整数型数据长度

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long client = ola.TcpClientCreate(nullptr, 0, 0);
ola.TcpClientConnect(client, "127.0.0.1", 9000);
// 发送 UTF-8 文本需自行准备 buffer 指针
ola.TcpClientSend(client, (long)dataPtr, dataLen);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long client = ola.TcpClientCreate(nullptr, 0, 0);
ola.TcpClientConnect(client, "127.0.0.1", 9000);
// 发送 UTF-8 文本需自行准备 buffer 指针
ola.TcpClientSend(client, (long)dataPtr, dataLen);
python
from OLAPlugServer import OLAPlugServer

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long client = TcpClientCreate(instance, nullptr, 0, 0);
TcpClientConnect(instance, client, "127.0.0.1", 9000);
TcpClientSend(instance, client, (long)dataPtr, dataLen);
csharp
long instance = CreateCOLAPlugInterFace();
long client = TcpClientCreate(instance, nullptr, 0, 0);
TcpClientConnect(instance, client, "127.0.0.1", 9000);
TcpClientSend(instance, client, (long)dataPtr, dataLen);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
client = TcpClientCreate(instance, nullptr, 0, 0)
TcpClientConnect(instance, client, "127.0.0.1", 9000)
TcpClientSend(instance, client, (long)dataPtr, dataLen)

返回值 ​

整数型，1 成功（加入发送队列），0 失败。

注意事项 ​

  • 这是异步操作，数据会被加入发送队列
  • 发送完成后会触发回调（event_type=4）
  • 如果启用了分包协议，会自动添加4字节长度前缀
  • 如果未连接，发送会失败
  • 数据会被复制，调用后可以立即释放原始数据
