這樣解決：

建立一個頭文件kbhit.h

內容如下：

#ifndef KBHITh

#define KBHITh

void init_keyboard(void);

void close_keyboard(void);

int kbhit(void);

int readch(void);

#endif

然后建立源文件kbhit.c

內容如下：

#include "kbhit.h"

#include

#include // for read()

static struct termios initial_settings, new_settings;

static int peek_character = -1;

void init_keyboard()

{

tcgetattr(0,&initial_settings);

new_settings = initial_settings;

new_settings.c_lflag &= ~ICANON;

new_settings.c_lflag &= ~ECHO;

new_settings.c_lflag &= ~ISIG;

new_settings.c_cc[VMIN] = 1;

new_settings.c_cc[VTIME] = 0;

tcsetattr(0, TCSANOW, &new_settings);

}

void close_keyboard()

{

tcsetattr(0, TCSANOW, &initial_settings);

}

int kbhit()

{

unsigned char ch;

int nread;

if (peek_character != -1) return 1;

new_settings.c_cc[VMIN]=0;

tcsetattr(0, TCSANOW, &new_settings);

nread = read(0,&ch,1);

new_settings.c_cc[VMIN]=1;

tcsetattr(0, TCSANOW, &new_settings);

if(nread == 1)

{

peek_character = ch;

return 1;

}

return 0;

}

int readch()

{

char ch;

if(peek_character != -1)

{

ch = peek_character;

peek_character = -1;

return ch;

}

read(0,&ch,1);

return ch;

}

將這兩個文件放到你的工程目錄下，包含頭文件就可以調用kbhit()函數了

祝你好運
