NAME
       idn2_to_unicode_44i - API function

SYNOPSIS
       #include <idn2.h>

       int idn2_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 UTF-32 code points.

       size_t inlen
                   number of code points of input array

       uint32_t * out
                   output array with UTF-32 code points.

       size_t * outlen
                   on input, maximum size of output array with UTF-32 code
                   points, on exit, actual size of output array with UTF-32
                   code points.

       int flags   Currently unused.

DESCRIPTION
       The ToUnicode operation takes a sequence of UTF-32 code points that
       make up one domain label and returns a sequence of UTF-32 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.

        output may be NULL to test lookup of  input without allocating memory.

SINCE
       2.0.0
