       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 AllowUnas‐
       signed flag, and the UseSTD3ASCIIRules flag. The output of  ToASCII  is
       either a sequence of ASCII code points or a failure condition.

       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 apply‐
       ing it just once.

       Returns 0 on success, or an Idna_rc error code.
