       idna_to_ascii_4i - API function

       #include <idna.h>

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

       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 IDNA_USE_STD3_ASCII_RULES.

       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 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 applying it just once.

       Returns 0 on success, or an Idna_rc error code.
