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.
