我可以将哪些C ++标头用于这些特定功能？ Linux的

Question

I am linux user and would like to use these 'keyboard_event' functions, but the header for these functions is 'windows.h' and linux doesn't have any 'windows.h', so can anyone support some alternative header for these functions, or alternative way to simulate key press for linux ?

#include <iostream>
using namespace std;

int main() {

    keybd_event(VK_CONTROL,0x9d,0 , 0); //pressing CTRL
    keybd_event(VkKeyScan(‘R’),0x93,0 , 0); //pressing 'R'
    keybd_event(VkKeyScan(‘R’),0x93,KEYEVENTF_KEYUP,0); //releasing 'R'
    keybd_event(VK_CONTROL,0x9d,KEYEVENTF_KEYUP,0); /* releasing CTRL */


    return;
}

Answer 1

There's no "equivalent" for windows.h in Linux. You need to fix your errors case by case, or better, rewrite your code for Linux.

Answer 2

uinput内核模块和libevdev就是为了这个目的而引入的。

Answer 3

I've found a solution, in code I just type:

system("xte 'keydown Control_L' 'key R' 'keyup Control_L'");

and it does the same, but <cstdlib> has to be included.

Answer 4

I don't know what "keyboard_event" functions are but i guess this would be helpful:

#include <iostream>
#include <cstdio> // for getchar()
#include <unistd.h> // for getch()
#include <termios.h> // for getch()

using namespace std;

int getch();
int main()
{
    int ch = getch();
    cout << ch << endl;
}

int getch()
{
    struct termios oldt, newt;
    int ch;
    tcgetattr(STDIN_FILENO, &oldt);
    newt = oldt;
    newt.c_lflag &= ~(ICANON | ECHO);
    tcsetattr(STDIN_FILENO, TCSANOW, &newt);
    ch = getchar();
    tcsetattr(STDIN_FILENO, TCSANOW, &oldt);
    return ch;
}
