ulabel: input zero-terminated UTF-8 and Unicode NFC 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 must be encoded in UTF-8 and be in Unicode NFC form.
flags to convert input
ulabel to NFC form
before further processing.
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, or another error code is returned.
