tld_check_8z(3) libidn tld_check_8z(3) NAME tld_check_8z - API function SYNOPSIS #include <tld.h> int tld_check_8z(const char * in, size_t * errpos, const Tld_table ** overrides); ARGUMENTS const char * in Zero-terminated UTF8 string to process. 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 characters 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 . Note that the error position refers to the decoded character offset rather than the byte position in the string. Return value: Returns the Tld_rc value TLD_SUCCESS if all characters are valid or when tld is null, TLD_INVALID if a character is not al- lowed, or additional error codes on general failure conditions.
