如何在Win32函数成功后从PWSTR中检索字符串？

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

int main()
{
    PWSTR pwszString = L"Hello, World!"; // 假设这是一个PWSTR字符串

    // 确定字符串长度
    int length = wcslen(pwszString);

    // 创建缓冲区
    int bufferSize = WideCharToMultiByte(CP_UTF8, 0, pwszString, length, NULL, 0, NULL, NULL);
    char* pszString = new char[bufferSize + 1];

    // 转换为多字节字符串
    WideCharToMultiByte(CP_UTF8, 0, pwszString, length, pszString, bufferSize, NULL, NULL);
    pszString[bufferSize] = '\0'; // 添加字符串结束符

    // 输出多字节字符串
    std::cout << "Multi-byte string: " << pszString << std::endl;

    delete[] pszString; // 释放内存

    return 0;
}
