c++创建多级目录

c++创建多级目录实现：

BOOL CCommonFunctions::CreateDirectories(const TCHAR *strPathName,BOOL blFile)
{
    CString pathName = strPathName;

    //不是以"\"结尾的目录则添加"\"
    if(pathName.Right(1) != _T("\\") && !blFile)
    {
        pathName += _T("\\");
    }

    int end = pathName.ReverseFind('\\');
    int pt = pathName.Find('\\');

    if(pt > 0 && pathName[pt - 1] == ':')
    {
        pt = pathName.Find('\\', pt + 1);
    }
    else if(pathName[pt + 1] == '\\')
    {
        pt = pathName.Find('\\', pt + 2);
        pt = pathName.Find('\\', pt + 1);
    }

    CString path;
    while(pt != -1 && pt <= end)
    {
        path = pathName.Left(pt + 1);

        SetFileAttributes(path,FILE_ATTRIBUTE_NORMAL);
        if(!IsFolderExist(path))
        {
            //创建某级目录失败
            if(!CreateDirectory(path, NULL))
            {
                return FALSE;
            }
        }

        pt = pathName.Find('\\', pt + 1);
    }

    return TRUE;
}
