idn2_lookup_ul(3) libidn2 idn2_lookup_ul(3)NAMEidn2_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.
