文件重命名(C++源码)

1、调用示例

    // 调用示例
    // 文件重命名
    std::wstring strOldFileName = L"E:\\test.json";
    std::wstring strNewFileName = L"E:\\testNew.json";
    BOOL bReplaceIfExists = FALSE;
    BOOL ret = MyFileUtil::ReNameFile(strOldFileName, strNewFileName, bReplaceIfExists);
    std::cout << "ret:" << ret <<std::endl;

2、源码

BOOL MyFileUtil::ReNameFile(const std::wstring& strOldFileName, const std::wstring& strNewFileName, BOOL bReplaceIfExists)
{
    if (strOldFileName.empty() || strNewFileName.empty())
    {
        return FALSE;
    }

    DWORD dwFlags = MOVEFILE_COPY_ALLOWED;
    if (bReplaceIfExists)
    {
        dwFlags |= MOVEFILE_REPLACE_EXISTING;
    }
    return ::MoveFileExW(strOldFileName.c_str(), strNewFileName.c_str(), dwFlags);
}
