struct file结构体中包含有struct file_operations结构体,struct file_operations是struct file的一个域;我们在使用系统调用open()打开一个设备节点struct inode时,我们会得到一个文件struct file,同时返回一个文件描述符,该文件描述符是一个整数,我们称之为句柄,通过访问句柄我们能够访问设备文件struct file,描述符是一...
// indicated end-of-file by itself, allows the stream to close. // This does not cancel pending read operations, and if there is such an // operation, the process may still not be able to exit successfully // until it finishes. stream.push(null); stream.read(0); }, 100); 如果au...
-->f_path里存储的是open传入的路径,VFS就是根据这个路径逐层找到相应的inode-->f_inode里存储的是找到的inode-->f_op里存储的就是驱动提供的file_operations对象,这个对象应该在第一次open()的时候被填充,具体地,应用层的open通过层层搜索会调用inode.i_fops->open(),即我们注册的open接口函数chrdev_open()...
