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 ;).
