NAME
idna_to_unicode_44i - API function SYNOPSIS
#include <idna.h> int idna_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t * out, size_t * outlen, int flags); ARGUMENTS
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. DESCRIPTION
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 points. RETURN VALUE
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 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. REPORTING BUGS

NAME
idna_to_ascii_4i - API function SYNOPSIS
#include <idna.h> int idna_to_ascii_4i(const uint32_t * in, size_t inlen, char * out, int flags); ARGUMENTS
const uint32_t * in input array with unicode code points. size_t inlen length of input array with unicode code points. char * out output zero terminated string that must have room for at least 63 characters plus the terminating zero. int flags an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES. DESCRIPTION
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. REPORTING BUGS
