Using SCODB

Following linked lists

Use the -> field argument to specify that the structure is a linked list, with field given as the ``next'' pointer. In this case, struct prints a structure at address, then another at *(address+(field offset)), and so on.

For example, to dump the STREAMS data block freelist as a linked list following the db_freep member of the structure:

   debug0:2> struct datab -> db_freep &dbfreelist

If structure fields are given (other than that required by the -> argument, if present), only those members of the structure are printed (in this example, db_freep is listed twice, once to declare it as the ``next'' pointer, once to have it printed):

   debug0:3> struct datab -> db_freep db_freep db_base &dbfreelist
   struct datab size = 10 bytes
   D00F072C:
           0000  0000 struct datab *db_freep   D00EFB18
           0004  0004 unsigned char *db_base   D00EEB18
   
   D00EFB18:
           0000  0000 struct datab *db_freep   00000000
           0004  0004 unsigned char *db_base   D12D5BFC
   End of list reached.
