idna_to_unicode_44i: API function
NAMEidna_to_unicode_44i - API function
- const uint32_t * in
- input array with unicode code points.
- size_t inlen
- 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.
DESCRIPTIONThe 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.
RETURN VALUEReturns 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 specification (sans malloc induced errors). NB! This means that you normally ignore the return code from this function, as checking it means breaking the standard.
