ulabel: input zero-terminated locale encoded string, or NULL.
alabel: input zero-terminated ACE encoded string (xn–), or NULL.
insertname: newly allocated output variable with name to register in DNS.
idn2_flags to modify behaviour.
Perform IDNA2008 register string conversion on domain label
alabel , as described in section 4 of RFC 5891. Note that the
ulabel 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.
It is recommended to supply both
alabel for better
error checking, but supplying just one of them will work. Passing
alabel is better than only
ulabel . See RFC 5891 section
4 for more information.
After version 0.11:
insertname may be NULL to test conversion of
src without allocating memory.
Returns: On successful conversion
IDN2_OK is returned, when the
alabel does not match each other
IDN2_UALABEL_MISMATCH is returned, when either of the input
labels are too long
IDN2_TOO_BIG_LABEL is returned, when
alabel does does not appear to be a proper A-label
is returned, when
ulabel locale to UTF-8 conversion failed
IDN2_ICONV_FAIL is returned, or another error code is returned.
