unnamed prototyped parameters not allowed when body is present

  Wrote a piece of code , I thought there was nothing wrong , The result is wrong ：

: error:  #141-D: unnamed prototyped parameters not allowed when body is present

Check the results , Use a third-party library , Actually put code Defined as a macro

  Just change the local variable definition of the function just now

This error occurred , It is usually caused by the conflict between variable and macro names
