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  addi-
       tional error codes on general failure conditions.
