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  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 ex-
       ercise for the reader ;).
