[ C#, C++ ] thread, async, Parallel

c++ thread, async 예시

//C++
#include <iostream>
#include <future>

// 쓰레드 사용시,  client list 벡터
std::vector<std::thread*> clientlist;
wsa wsa;

// 쓰레드 버전
clientlist.push_back(new std::thread(&wsa::client, wsa, sock_connected, clientAddr, &clientlist));

// Async 사용시,  client list 벡터
a_clientlist.push_back(std::async(std::launch::async, &wsa::client, wsa, sock_connected, clientAddr, &clientlist));

c++ thread, async 비교

// c++ async
std::future<void> a = std::async(std::launch::async, for_print, 'a');
std::future<void> b = std::async(std::launch::deferred, for_print, 'b');
b.get();
std::future<void> c = std::async(for_print, 'c');

 wsa temp;
// c++ thread
new std::thread(&wsa::Recv_, temp, clientSock);
// c++ async
std::future<wchar_t*> a = std::async(std::launch::async, &wsa::Recv_, temp, clientSock);

C# Parallel

// 단순 병렬 분할 크기 전송

Parallel.For (0, cnt, i =>
{
    int start_index = i * 분할크기
    socket.Send(file_byte, start_index, 분할크기, SocketFlags.None);
});
