Just do this instead:

int (*pf)(struct cmd_tbl_s *, int, int, char *[]);

int do_ptrt (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) { if (!pf) pf = do_ptrt;

printf ("pointer is %p\n", pf); printf ("function is %p\n", do_ptrt); return 0; }

IMO, it's best to avoid such pointers in the first place, especially ones that are statically initialized.
