| Um.... maybe I'm being naive myself, but did you try the obvious one,
| the one you declared it with?  That is,
| 
|      (*t_xyz.p_cmd_blk)[N]

Um...isn't (*p_cmd_blk)[] an array of pointers, not a pointer to an array?
try *(p_cmd_blk[]).

K&R (old) Page 110 says that int *b[10] is an array of 10 pointers to int;
therefore, struct diag_cmd *p_cmd_blk[] should be an array of pointers to
struct diag_cmd.  Somehow I doubt that the parens around *p_cmd_blk are
grouping things differently.

Ayway, there's always struct diag_cmd **p_cmnd_blk.
