       1: /*
       2:  * File layouts for notesfiles:
       3:  *
       4:  * There are four files:
       5:  *
       6:  * 	text
       7:  * 		Contains a free pointer and all main note texts.  A debug
       8:  * 		aid is the note number, response number, and length assoc'd
       9:  * 		with each "page" stored.
      10:  *
      11:  * 	resp.indx
      12:  * 		Contains blocks of response pointers.
      13:  *
      14:  * 	note.indx
      15:  * 		Contains a) description of notesfile in general
      16:  * 			 b) all the note "headers" with titles and dates
      17:  * 			    and what not.
      18:  *
      19:  *	access
      20:  *		Contains the permission tables for the notefile
      21:  *
      22:  * General layout:
      23:  *
      24:  * 	text:    daddr_f (free pointer)
      25:  *
      26:  *		txthead_f
      27:  *		char text[];	<-- length determined by txthead_f
      28:  *
      29:  *		txthead_f;
      30:  *		char text[];
      31:  *
      32:  * 	resp.indx: int  (free pointer to next empty slot -- init 0)
      33:  * 		resp_f
      34:  * 		resp_f
      35:  * 		... resp_f * <--- these are pointed to by indexes in the
      36:  * 					note.indx file below.  Each is
      37:  * 					autonomous, though they might
      38:  * 					link to each other for more than
      39:  * 					25 responses to a note.
      40:  *
      41:  *
      42:  * 	note.indx: descr_f  (describes whole notesfile plus has some
      43:  * 				ongoing pointers and dates)
      44:  * 		note_f
      45:  * 		note_f
      46:  * 		... note_f * <---- these are indexed by note number.  They
      47:  * 				reference the resp_f's above by "response
      48:  * 				number" which must be *'d by sizeof resp_f.
      49:  *
      50:  *	access :
      51:  *		perm_f
      52:  *		perm_f	<--- contains NPERMS copies of this structure.
      53:  *			Each one gives a user, group or system. They
      54:  *			are sorted in order of precedence, so the first
      55:  *			one encountered is the correct one to give to
      56:  *			the user. There should not be MORE then NPERMS
      57:  *			entries in the table!
      58:  *
