NAME

6       tld_check_4 - API function
7

SYNOPSIS

9       #include <tld.h>
10
11       int  tld_check_4(const  uint32_t  *  in, size_t inlen, size_t * errpos,
12       const Tld_table ** overrides);
13

ARGUMENTS

15       const uint32_t * in
16                   Array of unicode code points to process. Does not  need  to
17                   be zero terminated.
18
19       size_t inlen
20                   Number of unicode code points.
21
22       size_t * errpos
23                   Position of offending character is returned here.
24
25       const Tld_table ** overrides
26                   A  Tld_table  array of additional domain restriction struc‐
27                   tures that complement and supersede the  built-in  informa‐
28                   tion.
29

DESCRIPTION

31       Test each of the code points in  in for whether or not they are allowed
32       by the information in  overrides or by  the  built-in  TLD  restriction
33       data.  When  data  for the same TLD is available both internally and in
34       overrides , the information in  overrides takes precedence. If  several
35       entries for a specific TLD are found, the first one is used.  If  over‐
36       rides is NULL, only the built-in information is used.  The position  of
37       the first offending character is returned in  errpos .
38
39       Return  value:  Returns the Tld_rc value TLD_SUCCESS if all code points
40       are valid or when  tld is null, TLD_INVALID if a character is  not  al‐
41       lowed, or additional error codes on general failure conditions.
