I've got a feeling you are trying to dilute this exchange by
artificially introducing conceptual confusion. Just as Pilate asked:
„but what exactly is truth?” — you keep asking: „which actually
screen?”.
As I already answered: the one described by the parameters. ('display'
is a pointer to a 'Display' structure returned by a previous call to
XOpenDisplay() ). The parameters to functions we're talking about are
described as follows:
int DisplayHeight(Display *display, int screen_number);
int DisplayWidth(Display *display, int screen_number);
It's clearly defined there.
Say, we've got a simple program:
#include <X11/Xlib.h>
#include <stdio.h>
int main(int argc,char **argv) {
Display *display = XOpenDisplay(NULL);
int screen_number = DefaultScreen(display);
int height = DisplayHeight(display, screen_number);
int width = DisplayWidth(display, screen_number);
XCloseDisplay(display);
printf("Height: %d\n", height);
printf("Width: %d\n", width);
return 0;
}
What more you need to find out „which display”?
