NAME

6       tld_check_lz - API function
7

SYNOPSIS

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

ARGUMENTS

15       const char * in
16                   Zero-terminated string in the current locales  encoding  to
17                   process.
18
19       size_t * errpos
20                   Position of offending character is returned here.
21
22       const Tld_table ** overrides
23                   A  Tld_table  array of additional domain restriction struc‐
24                   tures that complement and supersede the  built-in  informa‐
25                   tion.
26

DESCRIPTION

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