FcCharSetFirstPage(3)                                    FcCharSetFirstPage(3)

NAME
       FcCharSetFirstPage - Start enumerating charset contents

SYNOPSIS
       #include <fontconfig/fontconfig.h>

       FcChar32     FcCharSetFirstPage     (const     FcCharSet     *a,    Fc-
       Char32[FC_CHARSET_MAP_SIZE] map, FcChar32 *next);

DESCRIPTION
       Builds an array of bits in map marking the first page of Unicode cover-
       age  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 FcCharSet-
       FirstPage 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 excercise for the reader ;).
