NAME

       tld_check_4 - API function

SYNOPSIS

       #include <tld.h>

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

ARGUMENTS

       const uint32_t * in
                   Array of unicode code points to process. Does not need to be zero terminated.

       size_t inlen
                   Number of unicode code points.

       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.
