need help to generate keystrokes into existing application in Linux environment using C++

Question

I need help to generate keystrokes in my existing application in LINUX environment. I am fully aware that there are libraries in Dev C++ which do exactly what I want but in Wind

What you want is create and initialize XKeyEvent struct and send it with XSendEvent.

Be sure to check man xkeyevent and man xsendevent

From man xkeyevent:

   typedef struct {
        int type;                /* KeyPress or KeyRelease */
        unsigned long serial;    /* # of last request processed by server */
        Bool send_event;         /* true if this came from a SendEvent request */
        Display *display;        /* Display the event was read from */
        Window window;           /* ``event'' window it is reported relative to */
        Window root;             /* root window that the event occurred on */
        Window subwindow;        /* child window */
        Time time;               /* milliseconds */
        int x, y;                /* pointer x, y coordinates in event window */
        int x_root, y_root;      /* coordinates relative to root */
        unsigned int state;      /* key or button mask */
        unsigned int keycode;    /* detail */
        Bool same_screen;        /* same screen flag */
   } XKeyEvent;

To get key keycodes, check /usr/include/X11/keysymdef.h ur just use xev

I found a brief introduction for you.

(Edit: It seems someone solved it already :))
