请使用c++写出内核驱动读写进程内存的代码

下面是c写出内核驱动读写进程内存的代码：#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/kprobes.h>
#include <linux/sched.h>
#include <linux/mm.h>static int read_write_process_memory(struct task_struct *task)
{
struct mm_struct *mm;
struct vm_area_struct *vma;
unsigned long start, end, total_size;
void *buf;
int err = 0; mm = get_task_mm(task);
if (!mm)
return -EINVAL; total_size = 0;
for (vma = mm->mmap; vma; vma = vma->vm_next) {
start = vma->vm_start;
end = vma->vm_end;
total_size += end - start; buf = kmalloc(end - start, GFP_KERNEL);
if (!buf) {
err = -ENOMEM;
goto out;
} // Read from process's memory.
if (copy_from_user(buf, (void *)start, end - start)) {
err = -EFAULT;
kfree(buf);
goto out;
} // Do something with buf. // Write to process's memory.
if (copy_to_user((void *)start, buf, end - start)) {
err = -EFAULT;
kfree(buf);
goto out;
} kfree(buf);
}out:
mmput(mm);
return err;
