tld_check_lz(3) 		     libidn			 tld_check_lz(3)

NAME
     tld_check_lz - API function

SYNOPSIS
     #include <tld.h>

     int tld_check_lz(const char * in, size_t * errpos, const Tld_table ** over-
     rides);

ARGUMENTS
     const char * in
		 Zero-terminated  string  in  the  current  locales  encoding 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 spe-
     cific 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.
