函数原型：int single_open(struct file *file, int (*show)(struct seq_file *, void *), void *data)

返回类型：int

参数：

类型参数名称
struct file *file
int (*show
void *data
569  op等于开辟内存
570  res等于负ENOMEM
572  如果op则
573  start等于single_start
574  next等于single_next
575  stop等于single_stop
576  show等于show
577  res等于seq_open - initialize sequential file*@file: file we initialize*@op: method table describing the sequence* seq_open() sets @file, associating it with a sequence described* by @op. @op->start() sets the iterator up and returns the first
578  如果非res则private等于data
580  否则释放内存
583  返回:res
