ARGUMENTS

15       const char * ulabel
16                   input zero-terminated locale encoded string, or NULL.
17
18       const char * alabel
19                   input zero-terminated ACE encoded string (xn--), or NULL.
20
21       char ** insertname
22                   newly allocated output variable with name  to  register  in

DESCRIPTION

28       Perform  IDNA2008 register string conversion on domain label ulabel and
29       alabel, as described in section 4 of RFC 5891.   Note  that  the  input
30       ulabel  is assumed to be encoded in the locale's default coding system,
31       and will be transcoded to UTF-8 and NFC normalized by this function.
32
33       It is recommended to supply both ulabel and  alabel  for  better  error
34       checking,  but  supplying  just one of them will work.  Passing in only
35       alabel is better than only ulabel.  See RFC 5891  section  4  for  more
36       information.
37

RETURNS

39       On successful conversion IDN2_OK is returned, when the given ulabel and
40       alabel does not match each  other  IDN2_UALABEL_MISMATCH  is  returned,
41       when  either  of  the  input  labels are too long IDN2_TOO_BIG_LABEL is
42       returned, when alabel does does not  appear  to  be  a  proper  A-label
43       IDN2_INVALID_ALABEL is returned, or another error code is returned.
