idna_to_ascii_4i(3)						      libidn						       idna_to_ascii_4i(3)

NAME

       idna_to_ascii_4i - API function

SYNOPSIS

       #include <idna.h>

       int idna_to_ascii_4i(const uint32_t * in, size_t inlen, char * out, int flags);

ARGUMENTS

       const uint32_t * in
		   input array with unicode code points.

       size_t inlen
		   length of input array with unicode code points.

       char * out  output zero terminated string that must have room for at least 63 characters plus the terminating zero.

       int flags   an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

DESCRIPTION

       The  ToASCII  operation	takes  a  sequence  of Unicode code points that make up one domain label and transforms it into a sequence of code
       points in the ASCII range (0..7F). If ToASCII succeeds, the original sequence and the resulting sequence are equivalent labels.

       It is important to note that the ToASCII operation can fail. ToASCII fails if any step of it fails. If any step of  the	ToASCII  operation
       fails  on  any  label in a domain name, that domain name MUST NOT be used as an internationalized domain name. The method for deadling with
       this failure is application-specific.

       The inputs to ToASCII are a sequence of code points, the AllowUnassigned flag, and the UseSTD3ASCIIRules flag. The  output  of  ToASCII	is
       either a sequence of ASCII code points or a failure condition.

       ToASCII never alters a sequence of code points that are all in the ASCII range to begin with (although it could fail). Applying the ToASCII
       operation multiple times has exactly the same effect as applying it just once.

RETURN VALUE

       Returns 0 on success, or an Idna_rc error code.

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  addi-
       tional error codes on general failure conditions.
