- * idna_to_ascii_4i - convert Unicode domain name label to text
- * @in: input array with unicode code points.
- * @inlen: length of input array with unicode code points.
- * @out: output zero terminated string that must have room for at
- *       least 63 characters plus the terminating zero.
- * @flags: an #Idna_flags value, e.g., %IDNA_ALLOW_UNASSIGNED or
- *   %IDNA_USE_STD3_ASCII_RULES.
- *
- * The ToASCII operation takes a sequence of Unicode code points that
- * make up one domain label and transforms it into a sequence of code
- * points in the ASCII range (0..7F). If ToASCII succeeds, the
- * original sequence and the resulting sequence are equivalent labels.
- *
- * It is important to note that the ToASCII operation can fail. ToASCII
- * fails if any step of it fails. If any step of the ToASCII operation
- * fails on any label in a domain name, that domain name MUST NOT be used
- * as an internationalized domain name. The method for deadling with this
- * failure is application-specific.
- *
- * The inputs to ToASCII are a sequence of code points, the AllowUnassigned
- * flag, and the UseSTD3ASCIIRules flag. The output of ToASCII is either a
- * sequence of ASCII code points or a failure condition.
- *
- * ToASCII never alters a sequence of code points that are all in the ASCII
- * range to begin with (although it could fail). Applying the ToASCII
- * operation multiple times has exactly the same effect as applying it just
- * once.
- *
- * Return value: Returns 0 on success, or an #Idna_rc error code.
