en_get_entry

Preface

It can express the status and offset of the memory page, determine whether there is a page missing or obtain its corresponding physical address.

Example

Please read to obtain MAPS before use

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";
}

The above code retrieves the entry for each page and prints the status of its present.

Missing page judgment

We can read the code in the link to determine the missing page.
