Linux，如何捕获屏幕并模拟鼠标移动

//sg//Solution using Xlib for those who use Linux#include <X11/Xlib.h>#include<stdio.h>#include<unistd.h>#include <stdlib.h>#include <string.h>#include <unistd.h>#include <X11/Xlib.h>#include <X11/Xutil.h>void mouseClick(int button){    Display *display = XOpenDisplay(NULL);    XEvent event;    if(display == NULL)    {        fprintf(stderr, "Cannot initialize the displayn");        exit(EXIT_FAILURE);    }    memset(&event, 0x00, sizeof(event));    event.type = ButtonPress;    event.xbutton.button = button;    event.xbutton.same_screen = True;    XQueryPointer(display, RootWindow(display, DefaultScreen(display)), &event.xbutton.root, &event.xbutton.window, &event.xbutton.x_root, &event.xbutton.y_root, &event.xbutton.x, &event.xbutton.y, &event.xbutton.state);    event.xbutton.subwindow = event.xbutton.window;    while(event.xbutton.subwindow)    {        event.xbutton.window = event.xbutton.subwindow;        XQueryPointer(display, event.xbutton.window, &event.xbutton.root, &event.xbutton.subwindow, &event.xbutton.x_root, &event.xbutton.y_root, &event.xbutton.x, &event.xbutton.y, &event.xbutton.state);    }    if(XSendEvent(display, PointerWindow, True, 0xfff, &event) == 0) fprintf(stderr, "Errorn");    XFlush(display);    usleep(100000);    event.type = ButtonRelease;    event.xbutton.state = 0x100;    if(XSendEvent(display, PointerWindow, True, 0xfff, &event) == 0) fprintf(stderr, "Errorn");    XFlush(display);    XCloseDisplay(display);}int main(int argc,char * argv[]) {    int x , y;    x=atoi(argv[1]);    y=atoi(argv[2]);    Display *display = XOpenDisplay(0);    Window root = DefaultRootWindow(display);    XWarpPointer(display, None, root, 0, 0, 0, 0, x, y);    mouseClick(Button1);    XFlush(display);    XCloseDisplay(display);    return 0;}

进行构建，然后模拟x的点击，y做：

$ ./a.out x y

即

$ g ++ -lX11 sgmousesim2.cpp

$ ./a.out 123 13
