NAME

6       FcCharSetFirstPage - Start enumerating charset contents

SYNOPSIS

9       #include <fontconfig/fontconfig.h>
10
11       FcChar32 FcCharSetFirstPage (const FcCharSet *a, FcChar32[FC_CHARSET_MAP_SIZE] map, FcChar32 *next);

DESCRIPTION

14       Builds an array of bits in map marking the first page of Unicode cover‐
15       age of a.  *next is set to contains the base code point  for  the  next
16       page in a. Returns the base code point for the page, or FC_CHARSET_DONE
17       if a contains no pages. As an example,  if  FcCharSetFirstPage  returns
18       0x300 and fills map with
19
20       0xffffffff 0xffffffff 0x01000008 0x44300002 0xffffd7f0 0xfffffffb 0xffff7fff 0xffff0003
21
22       Then  the  page  contains code points 0x300 through 0x33f (the first 64
23       code points on the page) because map[0] and map[1] both have all  their
24       bits set. It also contains code points 0x343 (0x300 + 32*2 + (4-1)) and
25       0x35e (0x300 + 32*2 + (31-1)) because map[2] has the 4th and 31st  bits
26       set.  The  code  points  represented by map[3] and later are left as an
27       excercise for the reader ;).
