idna_to_unicode_44i - API function
int idna_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t * out, size_t *
outlen, int flags);
const uint32_t * in
input array with unicode code points.
length of input array with unicode code points.
uint32_t * out
output array with unicode code points.
size_t * outlen
on input, maximum size of output array with unicode code points, on exit,
actual size of output array with unicode code points.
int flags an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.
The ToUnicode operation takes a sequence of Unicode code points that make up one domain
label and returns a sequence of Unicode code points. If the input sequence is a label in
ACE form, then the result is an equivalent internationalized label that is not in ACE
form, otherwise the original sequence is returned unaltered.
ToUnicode never fails. If any step fails, then the original input sequence is returned
immediately in that step.
The Punycode decoder can never output more code points than it inputs, but Nameprep can,
and therefore ToUnicode can. Note that the number of octets needed to represent a
sequence of code points depends on the particular character encoding used.
The inputs to ToUnicode are a sequence of code points, the AllowUnassigned flag, and the
UseSTD3ASCIIRules flag. The output of ToUnicode is always a sequence of Unicode code
Returns Idna_rc error condition, but it must only be used for debugging purposes. The
output buffer is always guaranteed to contain the correct data according to the specifica-
tion (sans malloc induced errors). NB! This means that you normally ignore the return
code from this function, as checking it means breaking the standard.
