我有一个问题希望能得到大家的帮助!在我的程序中:

do

{……

}while((kbhit())==0);

我想知道“kbhit（）”是什么意思？它不是子函数。希望能有哪位高手能给我帮助！谢谢！

----------------解决方案--------------------------------------------------------
我估计是库函数吧，我也没有用过这个函数！
----------------解决方案--------------------------------------------------------

原型：extern int kbhit(void); 用法：#include <stdio.h> 功能：检测按键 说明：检测键盘是否有键按下。 如果有键按下，则返回对应键值；否则返回零。 kbhit不等待键盘按键。无论有无按键都会立即返回。

也是网上找到的，我也没用过。

_kbhit

Checks the console for keyboard input.

int _kbhit( void );

Routine	Required Header	Compatibility
_kbhit	<conio.h>	Win 95, Win NT

For additional compatibility information, see Compatibility in the Introduction.

Libraries

LIBC.LIB	Single thread static library, retail version
LIBCMT.LIB	Multithread static library, retail version
MSVCRT.LIB	Import library for MSVCRT.DLL, retail version

Return Value

_kbhit returns a nonzero value if a key has been pressed. Otherwise, it returns 0.

Remarks

The _kbhit function checks the console for a recent keystroke. If the function returns a nonzero value, a keystroke is waiting in the buffer. The program can then call _getch or _getche to get the keystroke.

Example

/* KBHIT.C: This program loops until the user * presses a key. If _kbhit returns nonzero, a * keystroke is waiting in the buffer. The program * can call _getch or _getche to get the keystroke. */#include <conio.h>#include <stdio.h>void main( void ){   /* Display message until key is pressed. */   while( !_kbhit() )      _cputs( "Hit me!! " );   /* Use _getch to throw key away. */   printf( "\nKey struck was '%c'\n", _getch() );   _getch();}

Output

Hit me!! Hit me!! Hit me!! Hit me!! Hit me!! Hit me!! Hit me!!Key struck was 'q'
