包/评论评论

Question

我复制这个结构

typedef struct SDL_Surface { 
Uint32 flags; /* Read-only */ 
SDL_PixelFormat *format; /* Read-only */ 
int w, h; /* Read-only */ 
Uint16 pitch; /* Read-only */ 
void *pixels; /* Read-write */ 
SDL_Rect clip_rect; /* Read-only */ 
8 int refcount; /* Read-mostly */ 
/* This structure also contains private fields not shown 
here */} SDL_Surface; 

，并试图评论（套）出以/ *和* /和开始和代码的结束，但它不会工作。

/* 
typedef struct SDL_Surface { //only commented out this line 
Uint32 flags; /* Read-only */ 
SDL_PixelFormat *format; /* Read-only */ 
int w, h; /* Read-only */ 
Uint16 pitch; /* Read-only */ 
void *pixels; /* Read-write */ 
SDL_Rect clip_rect; /* Read-only */ 
8 int refcount; /* Read-mostly */ 
/* This structure also contains private fields not shown 
here */} SDL_Surface; 
*/ 

任何人都可以帮我吗？

Answer 1

使用

#if 0 
blah 
#endif 

为 “注释” 的这样的代码大块。它也有可嵌套的好处。

（原因/*和*/不评论内部工作，是因为一次，第一*/将结束，所以/* blah /* explanation */ more */将explanation后结束，不more）

Answer 2

嵌套评论没有按”但是你可以让预处理器跳过struct

#if 0 

    typedef struct SDL_Surface { 
    Uint32 flags; /* Read-only */ 
    SDL_PixelFormat *format; /* Read-only */ 
    int w, h; /* Read-only */ 
    Uint16 pitch; /* Read-only */ 
    void *pixels; /* Read-write */ 
    SDL_Rect clip_rect; /* Read-only */ 
    8 int refcount; /* Read-mostly */ 
    /* This structure also contains private fields not shown 
    here */} SDL_Surface; 

#endif
