NAME
       get_font_ranges - Returns the number of character ranges in a font.
       Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       int get_font_ranges(FONT *f)

DESCRIPTION
       Use this function to find out the number of character ranges in a font.
       You should query each of these ranges with get_font_range_begin() and
       get_font_range_end() to find out what characters are available in the
       font. Example:

          FONT *f;
          int range;
          int n;
          ...

          range = get_font_ranges(f);
          printf("The font has %d character ranges:\n", range);
          for (n = 0; n < range; n++)
             printf("Range %d from 0x%03x - 0x%03x\n",
                    get_font_range_begin(f, n),
                    get_font_range_end(f, n));

RETURN VALUE
       Returns the number of continuous character ranges in a font, or -1 if
       that information is not available.
