嗨专家，
我在尝试访问

当你使用箭头操作符（ - >）时使用点运算符（。）
代替。

When you use a dot operator (.)
when you should be using an arrow operator (->)
instead.

也许你发布的代码和错误信息
我们有更多机会诊断你的问题。

perhaps if you posted the code and the error message
we would have more chance of diagnosing your problem.

当你有指向结构的指针时，你常常会看到类似的东西，
但是你假装它's struct。
time_t tt = time（NULL）;
struct tm * ptr = localtime（& tt）;
分钟= ptr.tm_min; / * error - ptr不是结构，而是指针* /
分钟= ptr-> tm_min; / *修复* /
当然，这只是一个猜测，确切的修复可能会有所不同，
取决于你的代码（我的我看不到。

Often you''ll see something of the kind when you have a pointer to a struct,
but you''re pretending it''s a struct.
time_t tt = time(NULL);
struct tm *ptr = localtime(&tt);
Minute = ptr.tm_min; /* error - ptr is not a struct, but a pointer */
Minute = ptr->tm_min; /* a fix */
Of course, this is really just a guess, and the exact fix may differ,
depending on your code (which I can''t see).
