NAME

       tld_check_4z - API function

SYNOPSIS

       #include <tld.h>

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

ARGUMENTS

       const uint32_t * in
                   Zero-terminated array of unicode code points to process.

       size_t * errpos
                   Position of offending character is returned here.

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

DESCRIPTION

       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.
