NAME

       FcCharSetFirstPage - Start enumerating charset contents

SYNOPSIS

       #include <fontconfig/fontconfig.h>

       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
       excercise for the reader ;).
