CopyMemory(tempCardArray[0],m_cbTableCardArray[INDEX_PLAYER],sizeof(m_cbTableCardArray[INDEX_PLAYER])); 这一段什么意思

这段代码使用了CopyMemory函数，将m_cbTableCardArray数组中的数据复制到tempCardArray数组中。

具体来说，CopyMemory的第一个参数是目标内存块的指针，这里是tempCardArray[0]，即tempCardArray数组的第一个元素的地址；第二个参数是源内存块的指针，这里是m_cbTableCardArray[INDEX_PLAYER]，即m_cbTableCardArray数组中玩家手牌的数组；第三个参数是要复制的字节数，这里使用了sizeof运算符获取了m_cbTableCardArray[INDEX_PLAYER]数组的大小。

因此，这段代码的作用是将m_cbTableCardArray数组中玩家手牌的数据复制到tempCardArray数组的第一个元素中。需要注意的是，tempCardArray数组必须有足够的空间来存储这些数据。

Windows调用API获取MINIDUMP_SYSTEM_INFO

要获取MINIDUMP_SYSTEM_INFO，您可以使用Windows API函数MiniDumpWriteDump和MiniDumpReadDumpStream。以下是一个示例代码片段，演示如何使用这些函数来获取MINIDUMP_SYSTEM_INFO：

// 定义MINIDUMP_SYSTEM_INFO结构体
typedef struct _MINIDUMP_SYSTEM_INFO {
  USHORT ProcessorArchitecture;
  USHORT ProcessorLevel;
  USHORT ProcessorRevision;
  USHORT Reserved0;
  ULONG64 CpuMaxMhz;
  ULONG64 CpuCurMhz;
  ULONG64 CpuLimitMhz;
  ULONG64 CpuAvgMhz;
  ULONG64 MemorySize;
  ULONG64 BootTime;
  ULONG64 SystemTime;
  ULONG64 TimeZoneBias;
  ULONG   TimeZoneId;
  ULONG   Reserved1[8];
} MINIDUMP_SYSTEM_INFO, *PMINIDUMP_SYSTEM_INFO;

// 获取MINIDUMP_SYSTEM_INFO
BOOL GetMiniDumpSystemInfo(HANDLE hProcess, LPVOID lpMiniDumpBuffer, DWORD dwBufferSize, PMINIDUMP_SYSTEM_INFO pSystemInfo)
{
    DWORD dwStreamSize = 0;
    PVOID pStream = MiniDumpReadDumpStream(lpMiniDumpBuffer, SystemInfoStream, NULL, &dwStreamSize);
    if (pStream == NULL) {
        return FALSE;
    }

    if (dwStreamSize != sizeof(MINIDUMP_SYSTEM_INFO)) {
        return FALSE;
    }

    CopyMemory(pSystemInfo, pStream, dwStreamSize);

    return TRUE;
}

// 使用MiniDumpWriteDump生成MiniDump文件
BOOL GenerateMiniDump(HANDLE hProcess, DWORD dwProcessId, LPCWSTR lpFilePath)
{
    HANDLE hDumpFile = CreateFileW(lpFilePath, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

    if (hDumpFile == INVALID_HANDLE_VALUE) {
        return FALSE;
    }

    MINIDUMP_EXCEPTION_INFORMATION exceptionInfo = { 0 };
    exceptionInfo.ThreadId = GetCurrentThreadId();
    exceptionInfo.ExceptionPointers = NULL;
    exceptionInfo.ClientPointers = FALSE;

    BOOL bResult = MiniDumpWriteDump(hProcess, dwProcessId, hDumpFile, MiniDumpNormal, &exceptionInfo, NULL, NULL);

    CloseHandle(hDumpFile);

    return bResult;
}

// 使用示例
HANDLE hProcess = GetCurrentProcess();
DWORD dwProcessId = GetCurrentProcessId();
WCHAR szFilePath[MAX_PATH] = L"C:\\crash.dmp";

if (GenerateMiniDump(hProcess, dwProcessId, szFilePath))
{
    HANDLE hFile = CreateFileW(szFilePath, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    if (hFile != INVALID_HANDLE_VALUE)
    {
        DWORD dwFileSize = GetFileSize(hFile, NULL);
        LPVOID lpMiniDumpBuffer = VirtualAlloc(NULL, dwFileSize, MEM_COMMIT, PAGE_READWRITE);
        if (lpMiniDumpBuffer != NULL)
        {
            DWORD dwBytesRead = 0;
            if (ReadFile(hFile, lpMiniDumpBuffer, dwFileSize, &dwBytesRead, NULL))
            {
                MINIDUMP_SYSTEM_INFO systemInfo = { 0 };
                if (GetMiniDumpSystemInfo(hProcess, lpMiniDumpBuffer, dwFileSize, &systemInfo))
                {
                    // 在这里使用MINIDUMP_SYSTEM_INFO
                }
            }

            VirtualFree(lpMiniDumpBuffer, 0, MEM_RELEASE);
        }

        CloseHandle(hFile);
    }
}

请注意，上述示例代码仅用于说明如何获取MINIDUMP_SYSTEM_INFO，您需要根据您的具体情况进行修改和适应。
