int tld_check_4	(	const uint32_t *	in,
		size_t	inlen,
		size_t *	errpos,
		const Tld_table **	overrides
	)

tld_check_4 - verify that characters are permitted

Parameters:

	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.
	overrides	A Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

Test each of the code points in for whether or not they are allowed by the information in or by the built-in TLD restriction data. When data for the same TLD is available both internally and in , the information in takes precedence. If several entries for a specific TLD are found, the first one is used. If is NULL, only the built-in information is used. The position of the first offending character is returned in .

Return value: Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.

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

tld_check_4t - verify that characters are permitted

Parameters:

	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 for whether or not they are allowed by the data structure in , return the position of the first character for which this is not the case in .

Return value: Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.

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

tld_check_4tz - verify that characters are permitted

Parameters:

	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 for whether or not they are allowed by the data structure in , return the position of the first character for which this is not the case in .

Return value: Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.

int tld_check_4z	(	const uint32_t *	in,
		size_t *	errpos,
		const Tld_table **	overrides
	)

tld_check_4z - verify that characters are permitted

Parameters:

	in	Zero-terminated array of unicode code points to process.
	errpos	Position of offending character is returned here.
	overrides	A Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

Test each of the code points in for whether or not they are allowed by the information in or by the built-in TLD restriction data. When data for the same TLD is available both internally and in , the information in takes precedence. If several entries for a specific TLD are found, the first one is used. If is NULL, only the built-in information is used. The position of the first offending character is returned in .

Return value: Returns the Tld_rc value TLD_SUCCESS if all code points are valid or when is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.

int tld_check_8z	(	const char *	in,
		size_t *	errpos,
		const Tld_table **	overrides
	)

tld_check_8z - verify that characters are permitted

Parameters:

	in	Zero-terminated UTF8 string to process.
	errpos	Position of offending character is returned here.
	overrides	A Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

Test each of the characters in for whether or not they are allowed by the information in or by the built-in TLD restriction data. When data for the same TLD is available both internally and in , the information in takes precedence. If several entries for a specific TLD are found, the first one is used. If is NULL, only the built-in information is used. The position of the first offending character is returned in . 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 is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.

int tld_check_lz	(	const char *	in,
		size_t *	errpos,
		const Tld_table **	overrides
	)

tld_check_lz - verify that characters are permitted

Parameters:

	in	Zero-terminated string in the current locales encoding to process.
	errpos	Position of offending character is returned here.
	overrides	A Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

Test each of the characters in for whether or not they are allowed by the information in or by the built-in TLD restriction data. When data for the same TLD is available both internally and in , the information in takes precedence. If several entries for a specific TLD are found, the first one is used. If is NULL, only the built-in information is used. The position of the first offending character is returned in . 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 is null, TLD_INVALID if a character is not allowed, or additional error codes on general failure conditions.
