7.2 Core Functions

tld_check_4t

Function: int tld_check_4t (const uint32_t * in, size_t inlen, size_t * errpos, const Tld_table * tld)

in: Array of unicode code points to process. Does not need to be zero terminated.

inlen: Number of unicode code points.

errpos: Position of offending character is returned here.

tld: A Tld_table data structure representing the restrictions for which the input should be tested.

Test each of the code points in in for whether or not they are allowed by the data structure in tld, return the position of the first character for which this is not the case 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 additional error codes on general failure conditions.

tld_check_4tz

Function: int tld_check_4tz (const uint32_t * in, size_t * errpos, const Tld_table * tld)

in: Zero terminated array of unicode code points to process.

errpos: Position of offending character is returned here.

tld: A Tld_table data structure representing the restrictions for which the input should be tested.

Test each of the code points in in for whether or not they are allowed by the data structure in tld, return the position of the first character for which this is not the case 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 additional error codes on general failure conditions.
