Review Comment:
#define lib_stream_puts(stream, buf, len) \
_**(FAR struct lib_outstream_s *)**_(stream)->puts((FAR struct
lib_outstream_s *)(stream), buf, len)
I have a little doubt about this code, which variable does it decorate (FAR
struct lib_outstream_s *)
Does this lead to different results if the precedence of "->" and "()" is
not the same in C and C++, as deduced by operator precedence.
这段代码我有一点疑问, (FAR struct lib_outstream_s *) 这个类型转换修饰是那一个变量呢？
如果按照运算符优先级进行推导，在 C 和 C++ 中 “->” 和 “()” 的优先级并不相同，这是否会导致不同的结果。
