@dlsflh shall 确实是强制的，我和 should 混了

@dlsflh https://www.rfc-editor.org/rfc/rfc2119.html
1. MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.

2. MUST NOT This phrase, or the phrase "SHALL NOT", mean that the
definition is an absolute prohibition of the specification.

3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.

4. SHOULD NOT This phrase, or the phrase "NOT RECOMMENDED" mean that
there may exist valid reasons in particular circumstances when the
particular behavior is acceptable or even useful, but the full
implications should be understood and the case carefully weighed
before implementing any behavior described with this label.

@icyalala http://port70.net/~nsz/c/c99/n1256.html#4p2 If a ''shall'' or ''shall not'' requirement that appears outside of a constraint is violated, the behavior is undefined.

@betatabe must 才是必须，shall 没有强制性，早期的编译器实现就是没有初始化的，所以都需要调用 memset
