NAME

       idn2_to_ascii_lz - API function

SYNOPSIS

       #include <idn2.h>

       int idn2_to_ascii_lz(const char * input, char ** output, int flags);

ARGUMENTS

       const char * input
                   zero terminated input UTF-8 string.

       char ** output
                   pointer to newly allocated output string.

       int flags   optional idn2_flags to modify behaviour.

DESCRIPTION

       Convert  a domain name in locale's encoding 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.

RETURNS

       IDN2_OK on success, or error code.  Same as described in idn2_lookup_ul() documentation.

SINCE

       2.0.0
