ext2ed/ext2.descriptors

   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 available 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.
