我可以在C中获得“宏多态性”吗？

假设我有一个名为draw()的宏,我有2个结构,一个叫做圆圈,另一个叫做方形.有可能以某种方式做这样的事情：

#define draw() // can I get the text that's behind the macro?
//then maybe,with _Generic achieve this?


void draw_circle(struct circle);
void draw_square(struct square);

struct circle c;
struct square s;

c.draw();//draw is a macro. this time it is supposed to expand to draw_circle(c);
s.draw();//supposed to expand to draw_square(s);

EDIT_1：在阅读完答案之后,这是我到目前为止所做的.

}

还有其他部分,但这些是目前移植到这种新语法的部分.现在主要：

int main ( int argc,char * argv[] )
{
    int data[30];

    //line bellow has a compilation error: *expected a ')'*
    init ( r_arr,data,sizeof ( int ),30 );
}

什么意思预期’)’
你们可以查看宏语法吗？
关于_Generic,我今天学到了它,如果它有用的话,我肯定会使用它.

EDIT_2：发现严重错误,将修复它并再次编辑. Visual Studio正在更新(12GB ……)所以我目前无法构建任何东西. [迷你编辑]：我猜我至少修正了粗错误. [迷你编辑]我的代码中另一个非常奇怪的错误,我将名称标记字符串化,是吗？！现在纠正了.

EDIT_3：已经睡觉并且VS再次运行,我修复了宏,将编辑它们并注释掉错误的代码.现在我需要circle.draw()行为……任何想法？
