◆ tld_check_4()

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

tld_check_4:

Parameters
inArray of unicode code points to process. Does not need to be zero terminated.
inlenNumber of unicode code points.
errposPosition of offending character is returned here.
overridesA Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

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 additional error codes on general failure conditions.

◆ tld_check_4t()

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

tld_check_4t:

Parameters
inArray of unicode code points to process. Does not need to be zero terminated.
inlenNumber of unicode code points.
errposPosition of offending character is returned here.
tldA 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.

Definition at line 280 of file tld.c.

◆ tld_check_4tz()

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

tld_check_4tz:

Parameters
inZero terminated array of unicode code points to process.
errposPosition of offending character is returned here.
tldA 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_4z()

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

tld_check_4z:

Parameters
inZero-terminated array of unicode code points to process.
errposPosition of offending character is returned here.
overridesA Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

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 additional error codes on general failure conditions.

◆ tld_check_8z()

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

tld_check_8z:

Parameters
inZero-terminated UTF8 string to process.
errposPosition of offending character is returned here.
overridesA Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

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 @overrides 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 allowed, or additional error codes on general failure conditions.

◆ tld_check_lz()

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

tld_check_lz:

Parameters
inZero-terminated string in the current locales encoding to process.
errposPosition of offending character is returned here.
overridesA Tld_table array of additional domain restriction structures that complement and supersede the built-in information.

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 @overrides 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 allowed, or additional error codes on general failure conditions.

◆ tld_default_table()

const Tld_table* tld_default_table ( const char *  tld,
const Tld_table **  overrides 
)

tld_default_table:

Parameters

overridesAdditional zero terminated array of Tld_table info-structures for TLDs, or NULL to only use library default tables.

Get the TLD table for a named TLD, using the internal defaults, possibly overridden by the (optional) supplied tables.

Return value: Return structure corresponding to TLD @tld_str, first looking through @overrides then thru built-in list, or NULL if no such structure found.
