- Windows下c代码
#include <conio.h> #include <windows.h> #include <iostream> using namespace std; int main() { while (!_kbhit()) { cout << "Hit me!!" << endl; Sleep(50); } printf("\nKey struck was '%c'\n", _getch()); //_getch(); system("pause"); }
- Linux下
#include <stdio.h> #include <stdlib.h> #define TTY_PATH "/dev/tty" #define STTY_US "stty raw -echo -F " #define STTY_DEF "stty -raw echo -F " int get_char(); int get_char() { fd_set rfds; struct timeval tv; int ch = 0; FD_ZERO(&rfds); FD_SET(0, &rfds); tv.tv_sec = 0; tv.tv_usec = 10; //设置等待超时时间 //检测键盘是否有输入 if (select(1, &rfds, NULL, NULL, &tv) > 0){ ch = getchar(); } return ch; } int main(){ int ch = 0; system(STTY_US TTY_PATH); // esc=27 while(1){ ch = get_char(); if(ch != 0){ printf("%d\n\r",ch); } if(ch == 3){ system(STTY_DEF TTY_PATH); return 0; } } }
