键盘的消息？？一般的输入也算消息吧？不就是用if()来检测的么？难道你想输入其他的键？比如上下键 左右键？

#include <conio.h>
#include <windows.h>
void main() {
    unsigned short k;

    while (1) {
        Sleep(100);
        k=getch();
        if (27==k) break;//按Esc键退出
        if (0==k) k=getch()<<8;//非字符键
        cprintf("%04x pressed.\r\n",k);
    }
}

应该把问题说清楚一些啊~

上下左右键的输入

#include <conio.h>
#include <stdio.h>
int main()
{
 int c;    
 while(1)
 {
     c=getch();
  switch(c)
  {
        case 72:
            printf("up\n");
            break;
        case 75:
            printf("left\n");
            break;
        case 77:
            printf("right\n");
            break;
        case 80:     
            printf("down\n");
            break;
        case 27:  // ESC 
            return 1;    
  }
 }    
 return 0;  
}

The _getch function reads a single character from the console without echoing. _getche reads a single character from the console and echoes the character read. Neither function can be used to read CTRL+C. When reading a function key or an arrow key, _getch and _getche must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

#include <conio.h>
#include <windows.h>
void main() {
    unsigned short k;

    while (1) {
        Sleep(100);
        k=getch();
        if (27==k) break;//按Esc键退出
        if (0==k||0xe0==k) k|=getch()<<8;//非字符键
        cprintf("%04x pressed.\r\n",k);
    }
}
