NAME
       idn2_lookup_ul - API function

SYNOPSIS
       #include <idn2.h>

       int idn2_lookup_ul(const char * src, char ** lookupname, int flags);

ARGUMENTS
       const char * src
		   input zero-terminated locale encoded string.

       char ** lookupname
		   newly allocated output variable with name to lookup in DNS.

       int flags   optional idn2_flags to modify behaviour.

DESCRIPTION
       Perform	IDNA2008 lookup string conversion on domain name src, as described in section 5 of RFC 5891.  Note that the input is assumed to be
       encoded in the locale's default coding system, and will be transcoded to UTF-8 and NFC normalized by this function.

       Pass IDN2_ALABEL_ROUNDTRIP in flags to convert any input A-labels to U-labels and perform additional testing.

RETURNS
       On successful conversion IDN2_OK is returned, if conversion from locale to UTF-8 fails then IDN2_ICONV_FAIL  is	returned,  if  the  output
       domain or any label would have been too long IDN2_TOO_BIG_DOMAIN or IDN2_TOO_BIG_LABEL is returned, or another error code is returned.
