Is there a way of determining whether a font has variable or fixed
width?  The only way I could think of is by comparing the maximum and
minimum widths provided by the XFontStruc for the particular font.  Is
there a better way?

Thanks in advance,
Ari

Here is my program..

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

main (argc, argv)
int argc;
char **argv;
{
  Display *display;
  XFontStruct *font;

  if (argc < 2) {
    fprintf(stderr, "usage:  %s fontname.\n", argv[0]);
    exit(1);
  }

  if ((display = XOpenDisplay (NULL)) == NULL) {
    fprintf(stderr, "Can't open X display connection.\n");
    exit(1);
  }

  if ((font = XLoadQueryFont(display, argv[1])) == (XFontStruct *) NULL) {
    fprintf(stderr, "The font %s is not available.\n", argv[1]);
    XCloseDisplay(display);
    exit(1);
  }

  if (font ->min_bounds.width == font ->max_bounds.width)
    printf("%s is fixed width.\n", argv[1]);
  else
    printf("%s is not fixed width.\n", argv[1]);
    
  XFreeFont(display,font);
  XCloseDisplay(display);
  exit(0);
}
