Room Saving [by Reza Nejad]

From: The Dark One (Reza Nejad) <naxos@tiac.net>
Subject: Room Save Snippit

make a "save" directory in lib

----->in structs.h

add  #define ROOM_SAVE

(1 << 21) (or whatever the next number is)

if you use OasicOLC change num_room_flags one higher


------>Stick This in house.c

------>Add this to house.h

void    save_boot(void);
void    save_saved(int vnum);

-----> In db.c

in void_boot_db

add

  log("Loading Saved Rooms.");
  save_boot();

anywhere you like inside of the boot routines (I sugjest affter the house
loading)


------> In heartbeat() or do_save() or do_reboot() anywhere you find nice

   for(i=0;i <= top_of_world; i++) {
    if(IS_SET(ROOM_FLAGS(i), ROOM_SAVE))
     save_saved(i);
   }

*Note be sure to define "int i" and "extern int top_of_world" at the
 top of the function
