include:rtdef.h: comment Refine the annotation of RT_ALIGN and RT_ALIGN_DOWN (#10201)
include ：rtdef.h : [ Refine the annotation of RT_ALIGN and RT_ALIGN_DOWN ]
This macro is vulnerable to non-2-byte alignments,
but I assume that the macro definition was designed with an explicit use case of 2-byte alignments in mind.
Therefore, I only modify the comment to remind the user.
Solution:
RT_ALIGN(size, align) ((size) + (align) - 1) / (align) * (align)
RT_ALIGN_DOWN(size, align) (size) / (align) * (align)
Here's what deepseek recommends more.
