Today, I read chapter 1 "interrupt and interrupt handling procedures" and saw the spin_lock and spin_unlock, so I went into some in-depth research.
The spin_lock macro is defined as follows:

C/C ++ macro usage Summary
Macro replacement is the Technical Feature of the C/C ++ series languages. The C/C ++ language provides powerful macro replacement functions. Before the Source Code enters the compiler, first, a module called "Preprocessor"
People who are new to MFC programming are often intimidated by various macro definitions and preprocessing commands generated by the MFC wizard. However, preprocessing and macro definition are a powerful tool in C language. They can be used for
You can use macros to define "functions" without return values ". For example:
# Define printmax (A, B)/do/{/INT x = A, y = B;/printf ("MAX: % d/N", x> Y? X: Y); //} while (0) //... printmax (3, 4 );
Such a "function" is essentially different
