Just adding...
IMHO, you use "inline" if you plan to "insert" codes which is quite
long....so that in term of readability's point of view, it's easier to
read.
Just think by yourself, what happen if you met this kind of macro
(excuse me for some errors :D :D ):
#define iwonderwhy do {
i_need_to_do_this;
i++;
y++;
i_need_to_do_that;
and_another_that;
yet_another_that;
i_promise_this_is_the_end;
i_change_my_mind_again;
ok_here_is_the_end;
i=0
y=0
__repeat_the_above_steps_ten_times_explicitly
__great_i_gave_up
} while 0;
