zh_get_page_entry

页表项

页表项，可以表达该内存页的状态与偏移，可判断是否缺页或者获取其对应物理地址。

例子

使用前请阅读获取MAPS

获取Entry

std::string packageName = "bin.mt.plus";
try {
   auto pid = hak::find_process(packageName);
   std::cout << "pid: " << pid << "\n";
   auto process = std::make_shared<hak::process>(pid);
   process->set_memory_mode(memory_mode::SYSCALL);

   auto maps = process->get_maps();
   do {
        for (int i = 0; i < ((maps->end() - maps->start()) / getpagesize()); ++i) {
            auto entry = process->get_page_entry(maps->start() + i * getpagesize());
            std::cout << "present = " << entry.present << "\n";
        }
   } while ((maps = maps->next()));
} catch (std::exception& e) {
   std::cout << "error: " << e.what() << "\n";
}

上面的代码获取了每一页的entry并打印了其present的状态。
