int simkey(int fd,int value);

int main(void)
{


int fd_kbd;
char c;



if((fd_kbd=open("/dev/input/event1",O_RDWR ))<=0) //ls /dev/input/event1是存在的
{
printf("can not open kbd file !\n");
return -1;
}
if(simkey(fd_kbd,1)<0)
{
printf("No press !\n");
return -1;
}
if(simkey(fd_kbd,0)<0)
{
printf("No release!\n");
return -1;
}

close(fd_kbd);


printf("YES!\n");


return 0;
}
int simkey(int fd,int value)
{
struct input_event event;
event.type=EV_KEY;
event.code=KEY_A; //模拟输入'A'
event.value=value;
gettimeofday(&event.time,0);

if(write(fd,&event,sizeof(event))<0)
{
printf("simulate key error! \n");
return -1;
}

return 0;
}

使用sudo执行即可[luther.gliethttp]
