NAME

6       tld_check_4z - API function
7

SYNOPSIS

9       #include <tld.h>
10
11       int  tld_check_4z(const uint32_t * in, size_t * errpos, const Tld_table
12       ** overrides);
13

ARGUMENTS

15       const uint32_t * in
16                   Zero-terminated array of unicode code points to process.
17
18       size_t * errpos
19                   Position of offending character is returned here.
20
21       const Tld_table ** overrides
22                   A Tld_table array of additional domain  restriction  struc‐
23                   tures  that  complement and supersede the built-in informa‐
24                   tion.
25

DESCRIPTION

27       Test each of the code points in  in for whether or not they are allowed
28       by  the  information  in   overrides or by the built-in TLD restriction
29       data. When data for the same TLD is available both  internally  and  in
30       overrides  , the information in  overrides takes precedence. If several
31       entries for a specific TLD are found, the first one is used.  If  over‐
32       rides  is NULL, only the built-in information is used.  The position of
33       the first offending character is returned in  errpos .
34
35       Return value: Returns the Tld_rc value TLD_SUCCESS if all  code  points
36       are  valid  or when  tld is null, TLD_INVALID if a character is not al‐
37       lowed, or additional error codes on general failure conditions.
