tld_check_4(3)                      libidn                      tld_check_4(3)

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.
