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 ;).
