tld_check_4(3) libidn tld_check_4(3) NAME tld_check_4 - verify that characters are permitted 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 struc- tures that complement and supersede the built-in informa- tion. 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 over- rides 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.
