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:
", range);
	  for (n = 0; n < range; n++)
	     printf("Range %d from 0x%03x - 0x%03x
",
		    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.
