Excelentni napoveda :) Uz jsem to spachal. Dik

#include X11/Xlib.h
#include X11/Xutil.h
#include stdio.h

int main(void) {
	Display *display;
	Window focus;
	XWindowAttributes win_attr;
	Atom atom,actual_type;

        char *atom_name;
	int revert;
	int actual_format;
        unsigned long nitems;
        unsigned long bytes_after;
        unsigned char *prop;
        int status;
        int pid;

	display = XOpenDisplay(NULL);

	XGetInputFocus(display, &focus, &revert);
	XGetWindowAttributes(display, focus, &win_attr);

	atom = XInternAtom(display, "_NET_WM_PID", True);
        atom_name = XGetAtomName (display, atom);

                                                        
        status = XGetWindowProperty(display, focus, atom, 0, 1024,
                                    False, AnyPropertyType,
                                    &actual_type,
                                    &actual_format, &nitems,
                                    &bytes_after,
                                    &prop);

        pid = prop[1] * 256; 
        pid += prop[0];
        printf("pid of window 0x%x = %d\n",focus,pid);
	printf("%dpx x %dpx\n",win_attr.width,win_attr.height);

        return 0;
}
