       idna_to_ascii_4i - API function


       #include <idna.h>

       int idna_to_ascii_4i(const uint32_t * in, size_t inlen, char * out, int


       const uint32_t * in
                   input array with unicode code points.

       size_t inlen
                   length of input array with unicode code points.

       char * out  output zero terminated string that must have  room  for  at
                   least 63 characters plus the terminating zero.

       int flags   an   Idna_flags   value,   e.g.,  IDNA_ALLOW_UNASSIGNED  or


       The ToASCII operation takes a sequence of Unicode code points that make
       up one domain label and transforms it into a sequence of code points in
       the ASCII range (0..7F). If ToASCII succeeds, the original sequence and
       the resulting sequence are equivalent labels.

       It  is  important  to note that the ToASCII operation can fail. ToASCII
       fails if any step of it fails. If any step  of  the  ToASCII  operation
       fails  on any label in a domain name, that domain name MUST NOT be used
       as an internationalized domain name. The method for deadling with  this
       failure is application-specific.

       The   inputs   to   ToASCII   are   a  sequence  of  code  points,  the
       AllowUnassigned flag, and the UseSTD3ASCIIRules  flag.  The  output  of
       ToASCII  is  either  a  sequence  of  ASCII  code  points  or a failure

       ToASCII never alters a sequence of code points  that  are  all  in  the
       ASCII  range  to  begin  with  (although  it  could fail). Applying the
       ToASCII operation  multiple  times  has  exactly  the  same  effect  as
       applying it just once.


       Returns 0 on success, or an Idna_rc error code.
