NAME

       tld_check_8z - API function

SYNOPSIS

       #include <tld.h>

       int tld_check_8z(const char * in, size_t * errpos, const Tld_table ** overrides);

ARGUMENTS

       const char * in
                   Zero-terminated UTF8 string 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 characters 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 .  Note that the error position refers to the
       decoded character offset rather than the byte position in the string.

       Return value: Returns the Tld_rc value TLD_SUCCESS if all characters  are  valid  or  when
       tld  is  null,  TLD_INVALID  if  a  character is not allowed, or additional error codes on
       general failure conditions.
