NAME

       idn2_to_ascii_4z - API function

SYNOPSIS

       #include <idn2.h>

       int idn2_to_ascii_4z(const uint32_t * input, char ** output, int flags);

ARGUMENTS

       const uint32_t * input
                   zero terminated input Unicode (UCS-4) string.

       char ** output
                   pointer to newly allocated zero-terminated output string.

       int flags   optional idn2_flags to modify behaviour.

DESCRIPTION

       Convert  UCS-4  domain name to ASCII string using the IDNA2008 rules.  The domain name may
       contain several labels, separated by dots.  The output buffer must be deallocated  by  the
       caller.

       The default behavior of this function (when flags are zero) is to apply the IDNA2008 rules
       without  the  TR46  amendments.  As  the  TR46  non-transitional  processing  is  nowadays
       ubiquitous,   when   unsure,   it   is   recommended   to  call  this  function  with  the
       IDN2_NONTRANSITIONAL and the IDN2_NFC_INPUT flags for compatibility with other software.

       Return value: Returns IDN2_OK on success, or error code.

SINCE

       2.0.0
