line 64 and 65 in include/command.h
extern cmd_tbl_t __u_boot_cmd_start;
extern cmd_tbl_t __u_boot_cmd_end;
definition of cmd_tbl_t is just one line above these. Why "extern" is used?
Thanks,
struct cmd_tbl_s {
char *name; /* Command Name */
int maxargs; /* maximum number of arguments */
int repeatable; /* autorepeat allowed? */
/* Implementation function */
int (*cmd)(struct cmd_tbl_s *, int, int, char *[]);
char *usage; /* Usage message (short) */
#ifdef CONFIG_SYS_LONGHELP
char *help; /* Help message (long) */
#endif
#ifdef CONFIG_AUTO_COMPLETE
/* do auto completion on the arguments */
int (*complete)(int argc, char *argv[], char last_char, int
maxv, char
*cmdv[]);
#endif
};
