NAME
       idn2_lookup_u8 - API function

SYNOPSIS
       #include <idn2.h>

       int idn2_lookup_u8(const uint8_t * src, uint8_t ** lookupname, int flags);

ARGUMENTS
       const uint8_t * src
		   input zero-terminated UTF-8 string in Unicode NFC normalized form.

       uint8_t ** 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 string must be
       encoded in UTF-8 and be in Unicode NFC form.

       Pass IDN2_NFC_INPUT in flags to convert input to NFC form before further processing.  Pass IDN2_ALABEL_ROUNDTRIP in flags  to  convert  any
       input  A-labels	to  U-labels  and perform additional testing.  Multiple flags may be specified by binary or:ing them together, for example
       IDN2_NFC_INPUT | IDN2_ALABEL_ROUNDTRIP.

RETURNS
       On successful conversion IDN2_OK 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.
