Reads all the bytes from a file. The method ensures that the file is closed when all bytes have been read or an I/O error, or other runtime exception, is thrown. Note that this method is intended for simple cases where it is convenient to read all bytes into a byte array. It is...

例如read,write,那么映射到VFS中就是sys_read,sys_write,那么VFS可以根据你操作的是哪个“实际文件系统”(哪个分区)来进行不同的实际的操作!这个技术也是很熟悉的“钩子结构”技术来处理的。 其实就是VFS中提供一个抽象的struct结构体,然后对于每一个具体的文件系统要把自己的字段和函数填充进去,这样就解决了异构问...
