我正在尝试打印到我用 winapi 创建的新屏幕缓冲区，但它会转到旧缓冲区并且不会显示在屏幕上，是否可以重定向cout到使用 winapi 创建的新屏幕缓冲区？

#include <iostream>
#include <Windows.h>

int main() {
    HANDLE stdBuf, nBuf;
    DWORD numberOfChars;

    stdBuf = GetStdHandle(STD_OUTPUT_HANDLE);
    nBuf = CreateConsoleScreenBuffer(GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL);

    SetConsoleActiveScreenBuffer(nBuf);
    SetStdHandle(STD_OUTPUT_HANDLE, nBuf);

    // THIS SHOWING UP ON THE SCREEN
    WriteConsole(nBuf, "SECOND BUFFER", 13, &numberOfChars, NULL);

    // THIS IS GOING TO THE FIRST BUFFER
    std::cout << "SECOND BUFFER with cout" << std::endl;

    Sleep(3000);

    SetConsoleActiveScreenBuffer(stdBuf);
    CloseHandle(nBuf);

    int a = 0;
    std::cin >> a;
    return 0;
}
