为整个空间设定保护范围
原标题:Setting protection bits for the whole address space

在大韩民国,我想在这里做的只是让人们阅读到在含水层的地址中的所有页面。 每当写一个页时,我将在SIGSEGV信号手里给我写信。 在32个轨道上,由于地址空间仅为4GB,因此,为每一页留出一定时间,但我如何将这个问题放在64个轨道上,因为在此情况下,地址空间几乎是无限的。

如果我把地址面积限制在限定的-五上,那么我不会遇到任何问题,但有人告诉我,地址不是直线的。 现在,我的头脑 thinking着我如何能够解决这个问题。 在这方面的任何帮助将受到高度赞赏。 请告诉我,用最有效率的方式将64个比照方案的所有网页都读到。

最佳回答

为了避免保护整个空间,只保护使用的网页。 而且,由于该系统的陷阱,需要改变地址空间(地图、布莱克、可能read立的等等),以便你能够保护这些网页。

请注意,你的信号手无法运行,无法书写(也无法执行守则),因此存在一些根本问题,超过64个轨道。
