1 Extended 2 filesystem structure definitions for ext2ed. 2 3 Most of this file is just copied from the ext2 main include file. 4 5 My parser is very primitive - It only searches for the struct keywords, 6 and uses the variables in there. The rest of the file is just ignored. 7 8 You will find at the end a few additional types which are not aviable in 9 the original include file, such as the types "file" and "dir". They have 10 no variables, but are necessary due to the way ext2ed binds C commands 11 to specific types. 12 13 Gadi Oxman, 7/95 14 15 Here is the original copyright: 16 17 /* 18 * linux/include/linux/ext2_fs.h 19 * 20 * Copyright (C) 1992, 1993, 1994 Remy Card (card (a] masi.ibp.fr) 21 * Laboratoire MASI - Institut Blaise Pascal 22 * Universite Pierre et Marie Curie (Paris VI) 23 * 24 * from 25 * 26 * linux/include/linux/minix_fs.h 27 * 28 * Copyright (C) 1991, 1992 Linus Torvalds 29 */ 30 31 32 /* 33 * ACL structures 34 */ 35 struct ext2_acl_header /* Header of Access Control Lists */ 36 { 37 unsigned long aclh_size;
