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.
