Problem with transferring the socket as a flow argument

[jonetta]

When I hand over the socket as an argument, the flow accept gives a mistake 10061.

#include <iostream>
#pragma comment(lib, "ws2_32.lib")
#include <winsock2.h>
#include <ws2tcpip.h>
#include <thread>
#include <chrono>
#include <string>
std::string ip = "25.82.45.163";
wchar_t* toPCW(const std::string s)

{

const char* charArray = &s[0];

wchar_t* wString = new wchar_t[4096];

MultiByteToWideChar(CP_ACP, 0, charArray, -1, wString, 4096);

return wString;

}
void th1(int port) {

std::this_thread::sleep_for(std::chrono::seconds(1));

SOCKET s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

SOCKADDR_IN sock_addr;

InetPton(AF_INET, toPCW(ip), &sock_addr.sin_addr.s_addr);

sock_addr.sin_port = htons(port);

sock_addr.sin_family = AF_INET;

connect(s, (SOCKADDR*)&sock_addr, sizeof(sock_addr));

std::cout << "sent\n";

std::cout << WSAGetLastError() << '\n';

}
void th2(SOCKET s) {

listen(s, SOMAXCONN);
SOCKADDR c;
int size = sizeof(c);

SOCKET s1 = accept(s, &amp;c, &amp;size);
std::cout &lt;&lt; "recieved\n";
std::cout &lt;&lt; WSAGetLastError() &lt;&lt; '\n';

}
int main()

{

WSADATA WSAdata;

WORD DLLVersion = MAKEWORD(2, 1);

if (WSAStartup(DLLVersion, &WSAdata) != 0) {

std::cout << "EROR WSAStartup\n";

exit(1);

}
SOCKADDR_IN recv_TCP_addr;
recv_TCP_addr.sin_addr.s_addr = INADDR_ANY;
recv_TCP_addr.sin_port = 0;
recv_TCP_addr.sin_family = AF_INET;
int recv_TCP_size = sizeof(recv_TCP_addr);

SOCKET recv_TCP_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
bind(recv_TCP_socket, (SOCKADDR*)&amp;recv_TCP_addr, recv_TCP_size);

getsockname(recv_TCP_socket, (SOCKADDR*)&amp;recv_TCP_addr, &amp;recv_TCP_size);
int recv_port = recv_TCP_addr.sin_port;

std::thread th21(th2, recv_TCP_socket);
std::thread th11(th1, recv_port);
th21.detach();
th11.detach();

std::this_thread::sleep_for(std::chrono::seconds(10));

return 0;

}

But when I turn the flow only to the port and I'm already in the flow, I'm creating a juket and the binja works.

return wString;

}

if (WSAStartup(DLLVersion, &WSAdata) != 0) {

exit(1);

}

int recv_port = recv_TCP_addr.sin_port;

std::thread th21(th2, recv_port);
std::thread th11(th1, recv_port);
th21.detach();
th11.detach();

std::this_thread::sleep_for(std::chrono::seconds(10));

return 0;

}

What's the problem here, and is it possible to transfer the flow to a juket instead of a port?

[carriann]

In the first case, the number of the soket port that listens to the connection shall be transferred to the function. In terms int recv_port = recv_TCP_addr.sin_port; Total main The sket number has a web-based White order, but inside the function th1 Bite's order is turning. sock_addr.sin_port = htons(port); and the connection is taking place at another port.

In the second case, the same problem occurs twice, but in the function th2 A third juket is being created, which tries to listen to the port itself and the connection is fixed.

As they say, minus is a plus.
