FcCharSetFirstPage(3)					   FcCharSetFirstPage(3)

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 exercise for the
     reader ;).
