keyboard emulation function (C++) in linux OS ?

[jainpratik2]

Hi Folks,
I have stuck in problem. I want to record keyboard events like key up and key down in Linux OS but I couldnt able to find any proper answer.

I have got function but thats lib is very specific to Dev C++ in windows.

void GenerateKey(int vk , BOOL bExtended)
{
  KEYBDINPUT kb = {0};
  INPUT Input = {0};

  // generate down 
  if(bExtended)
    kb.dwFlags = KEYEVENTF_EXTENDEDKEY;
  kb.wVk = vk;  

  Input.type = INPUT_KEYBOARD;
  Input.ki = kb;
  ::SendInput(1, &Input, sizeof(Input));
  // generate up 
  ::ZeroMemory(&kb, sizeof(KEYBDINPUT));
  ::ZeroMemory(&Input, sizeof(INPUT));

  kb.dwFlags = KEYEVENTF_KEYUP;
  if(bExtended)
    kb.dwFlags |= KEYEVENTF_EXTENDEDKEY;

  kb.wVk = vk;
  Input.type = INPUT_KEYBOARD;
  Input.ki = kb;
  ::SendInput(1, &Input, sizeof(Input));
}

I exactly need code like this for my linux application.

Any ideas and suggestion will be of great help.

Thanks and regards,
jainp

This is not keyboard emulation (which would be GENERATING key presses), but rather just catching key presses, right?

Apparently this can be done using curses:

Hi Daviddoria,
Thanks a lot for quick reply. But the thing is, I have already written the code to capture the key events using ncurses and that was pretty straightforward. But here What i want is to simulate keyevents. If u look deeper into the above code , the code is simulating key press UP and down, So i want something like that.

I may be wrong , but What i draw conclusion from the above code is its pressing key and not capturing.

Thanks
