Hallo,
ich versuche mich gerade ein bisschen mit C. Leider bringt der Compiler
mit -W -Wall ein [segmention fault]. Ich habe wohl irgendwo was falsch
gemacht. Ich habe versucht ein bestehendes Programm um die
XGetInputFocus() Funktion zu erweitern. Dabei muss ich etwas übersehen
haben. Ich poste einfach mal den Quelltext und den Error:
#include <stdio.h>
#include <stdlib.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <string.h>
int main (int argc, char *argv[]) {
Display *display;
Window *focus_return;
int *revert_to_return;
int i;
if (argc<3) {
printf("usage: ./sendkey key1 key2 key3 etc.\n\n");
return(1);
}
if ((display = XOpenDisplay(NULL)) == NULL)
{
printf("Unable to open display\n");
return 1;
}
XGetInputFocus(display, focus_return,revert_to_return);
for (i=3; i<argc; ++i) {
XEvent ev;
KeySym key;
ev.xkey.type=KeyPress;
ev.xkey.window=(int)focus_return;
ev.xkey.root=ev.xkey.subwindow=None;
ev.xkey.time=0;
ev.xkey.x=ev.xkey.y=ev.xkey.x_root=ev.xkey.y_root=0;
ev.xkey.state=0;
key=XStringToKeysym(argv[i]);
ev.xkey.keycode=XKeysymToKeycode(display, key);
ev.xkey.same_screen=True;
XSendEvent(display, (int)focus_return, True, KeyPressMask, &ev);
ev.type=KeyRelease;
XSendEvent(display, (int)focus_return, True, KeyReleaseMask, &ev);
}
XCloseDisplay(display);
return(0);
}
Error:
