NAME

       idna_to_unicode_44i - API function

SYNOPSIS

       #include <idna.h>

       int idna_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t * out, size_t * outlen, int flags);

ARGUMENTS

       const uint32_t * in
                   input array with unicode code points.

       size_t inlen
                   length of input array with unicode code points.

       uint32_t * out
                   output array with unicode code points.

       size_t * outlen
                   on  input,  maximum  size  of  output array with unicode code points, on exit, actual size of
                   output array with unicode code points.

       int flags   an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

DESCRIPTION

       The ToUnicode operation takes a sequence of Unicode code points that make up one domain label and returns
       a  sequence  of  Unicode code points. If the input sequence is a label in ACE form, then the result is an
       equivalent internationalized label that is not in ACE form, otherwise the original sequence  is  returned
       unaltered.

       ToUnicode  never  fails.  If  any step fails, then the original input sequence is returned immediately in
       that step.

       The Punycode decoder can never output more code points than it inputs, but Nameprep  can,  and  therefore
       ToUnicode  can.   Note that the number of octets needed to represent a sequence of code points depends on
       the particular character encoding used.

       The  inputs  to  ToUnicode  are  a  sequence  of  code  points,  the  AllowUnassigned   flag,   and   the
       UseSTD3ASCIIRules flag. The output of ToUnicode is always a sequence of Unicode code points.

       Return  value:  Returns  Idna_rc  error  condition, but it must only be used for debugging purposes.  The
       output buffer is always guaranteed to contain the correct  data  according  to  the  specification  (sans
       malloc  induced errors).  NB!  This means that you normally ignore the return code from this function, as
       checking it means breaking the standard.
