以下是网络资料，还没经过测试

 

#include <stdio.h>

#include <termio.h>

 

static struct termio ttysave;

void restore(void);

char getch(void);

int main(void)

{.....}

 

char getch(void)

{

       static char ch;

       static int total,flag=1;

       struct termio tty;

       if (flag)

       {

              flag=0;

              if(ioctl(0,TCGETA,&tty)==-1)

              {

                     perror("ioctl");

                     exit(1);

              }

              ttysave=tty;

              tty.c_lflag &=~(ICANON|ECHO|ISIG);

              tty.c_cc[VMIN]=1;

              tty.c_cc[VTIME]=0;

              if(ioctl(0,TCSETAF,&tty)==-1)

              {

                     ..

                     perror("ioctl");

                     exit(2);

              }

       }

       switch(total=read(0,&ch,1))

       {

              case -1:

              ..;

              exit(3);

              case 0:

              fputs("EOF error!",stderr);

              exit(4);

              default:

              ;

       }

       ...

       return(ch);

}

 

 

 

第二种：

　　可以检测 PageUP PageDown以及Arrows等按键，F1, F2等功能键，
会被解释成输入一个字符序列。功能的实现是通过ioctl调整终端的属性。

 

#include <stdio.h>
#include <sys/ioctl.h>
#include <termios.h>

int getch( );

int main( )
{
    char ch;
    while(1){
        ch = getch( );
        printf("You Pressed %c\n", ch);
        if(ch == 'E')
             break;
    }
}

int getch()
{
    char ch;
    struct termios save, ne;
    ioctl(0, TCGETS, &save);
    ioctl(0, TCGETS, &ne);
    ne.c_lflag &= ~(ECHO | ICANON);
    ioctl(0, TCSETS, &ne);
    read(0, &ch, 1);
    ioctl(0, TCSETS, &save);
    return ch;
}
