c++代码inotify监管/proc/pid/pagemap

下面是一个使用inotify监控/proc/pid/pagemap的C++代码示例:
```c++
#include <unistd.h>
#include <sys/inotify.h>
#include <iostream>
#define EVENT_SIZE (sizeof(struct inotify_event))
#define BUF_LEN (1024 * (EVENT_SIZE + 16))
int main() {
int fd = inotify_init();
int wd = inotify_add_watch(fd, "/proc", IN_ALL_EVENTS);
char buf[BUF_LEN];
while (true) {
int length = read(fd, buf, BUF_LEN);
if (length < 0) {
std::cerr << "Error reading from inotify fd" << std::endl;
break;
}
for (char *p = buf; p < buf + length;) {
struct inotify_event *event = (struct inotify_event *)p;
std::cout << "Event: " << event->name << " - " << event->mask << std::endl;
if (event->mask & IN_ACCESS && std::string(event->name).find("pagemap") != std::string::npos) {
std::cout << "/proc/" << event->wd << "/pagemap was accessed" << std::endl;
}
p += EVENT_SIZE + event->len;
}
}
inotify_rm_watch(fd, wd);
close(fd);
return 0;
}
```
该程序使用inotify监控/proc目录下的所有事件,并在检测到访问/proc/pid/pagemap文件时输出相关信息。可以根据需要修改监控的目录和文件名。
