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
tld_check_4 - API function SYNOPSIS
#include <tld.h> int tld_check_4(const uint32_t * in, size_t inlen, size_t * errpos, const Tld_table ** overrides); ARGUMENTS
const uint32_t * in Array of unicode code points to process. Does not need to be zero terminated. size_t inlen Number of unicode code points. size_t * errpos Position of offending character is returned here. const Tld_table ** overrides A Tld_table array of additional domain restriction structures that complement and supersede the built-in information. DESCRIPTION
Test each of the code points in in for whether or not they are allowed by the information in overrides or by the built-in TLD restriction data. When data for the same TLD is available both internally and in overrides, the information in overrides takes precedence. If several entries for a specific TLD are found, the first one is used. If overrides is NULL, only the built-in information is used. The position of the first offending character is returned in errpos. RETURN VALUE
Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when tld is null, TLD_INVALID if a character is not allowed, or addi- tional error codes on general failure conditions. REPORTING BUGS
