11 int idn2_register_u8(const uint8_t * ulabel, const uint8_t * alabel,
12 uint8_t ** insertname, int flags);
13
15 const uint8_t * ulabel
16 input zero-terminated UTF-8 and Unicode NFC string, or
17 NULL.
18
19 const uint8_t * alabel
20 input zero-terminated ACE encoded string (xn--), or NULL.
21
22 uint8_t ** insertname
23 newly allocated output variable with name to register in
24 DNS.
25
26 int flags optional idn2_flags to modify behaviour.
27
29 Perform IDNA2008 register string conversion on domain label ulabel and
30 alabel , as described in section 4 of RFC 5891. Note that the input
31 ulabel must be encoded in UTF-8 and be in Unicode NFC form.
32
33 Pass IDN2_NFC_INPUT in flags to convert input ulabel to NFC form
34 before further processing.
35
36 It is recommended to supply both ulabel and alabel for better error
37 checking, but supplying just one of them will work. Passing in only
38 alabel is better than only ulabel . See RFC 5891 section 4 for more
39 information.
40
41 After version 0.11: insertname may be NULL to test conversion of src
42 without allocating memory.
43
45 On successful conversion IDN2_OK is returned, when the given ulabel
46 and alabel does not match each other IDN2_UALABEL_MISMATCH is
47 returned, when either of the input labels are too long
48 IDN2_TOO_BIG_LABEL is returned, when alabel does does not appear to be
49 a proper A-label IDN2_INVALID_ALABEL is returned, or another error code
50 is returned.
