Synopsis

FcChar32 FcCharSetFirstPage(const FcCharSet *a, FcChar32[FC_CHARSET_MAP_SIZE] map, FcChar32 *next);
Description
Builds an array of bits in map marking the
first page of Unicode coverage of a.
*next is set to contains the base code point
for the next page in a. Returns the base code
point for the page, or FC_CHARSET_DONE if
a contains no pages. As an example, if
FcCharSetFirstPage returns
0x300 and fills map with
0xffffffff 0xffffffff 0x01000008 0x44300002 0xffffd7f0 0xfffffffb 0xffff7fff 0xffff0003 |
Then the page contains code points
0x300 through
0x33f (the first 64 code points on the page)
because
map[0] and
map[1] both have all their bits set. It also
contains code points
0x343 (
0x300 + 32*2
+ (4-1)) and
0x35e (
0x300 +
32*2 + (31-1)) because
map[2] has
the 4th and 31st bits set. The code points represented by
map[3] and later are left as an exercise for the
reader ;).
