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.
