idn2_lookup_ul(3)		    libidn2		     idn2_lookup_ul(3)

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 de-
       scribed 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. This is default since version
       2.2.  To	switch this behavior off, pass IDN2_NO_ALABEL_ROUNDTRIP

       Pass IDN2_TRANSITIONAL to enable	Unicode	TR46 transitional  processing,
       and  IDN2_NONTRANSITIONAL  to enable Unicode TR46 non-transitional pro-
       cessing.

       Multiple	flags may be specified by binary or:ing	them together, for ex-
       ample IDN2_ALABEL_ROUNDTRIP | IDN2_NONTRANSITIONAL.

       The IDN2_NFC_INPUT in  flags is always enabled in this function.

       After  version  0.11:   lookupname  may	be NULL	to test	lookup of  src
       without allocating memory.

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.

SINCE
       0.1
