programming library.
#include <allegro.h>
int get_font_ranges(FONT *f)
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));
Returns the number of continuous character ranges in a font, or -1 if that
information is not available.
