NAME         top

       gnutls_idna_map - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_idna_map(const char * input, unsigned ilen, gnutls_datum_t
       * out, unsigned flags);

ARGUMENTS         top

       const char * input
                   contain the UTF-8 formatted domain name

       unsigned ilen
                   the length of the provided string

       gnutls_datum_t * out
                   the result in an null-terminated allocated string

       unsigned flags
                   should be zero

DESCRIPTION         top

       This function will convert the provided UTF-8 domain name, to its
       IDNA mapping in an allocated variable. Note that depending on the
       flags the used gnutls library was compiled with, the output of this
       function may vary (i.e., may be IDNA2008, or IDNA2003).

       To force IDNA2008 specify the flag GNUTLS_IDNA_FORCE_2008. In the
       case GnuTLS is not compiled with the necessary dependencies,
       GNUTLS_E_UNIMPLEMENTED_FEATURE will be returned to indicate that
       gnutls is unable to perform the requested conversion.

       Note also, that this function will return an empty string if an empty
       string is provided as input.

RETURNS         top

       GNUTLS_E_INVALID_UTF8_STRING on invalid UTF-8 data, or 0 on success.
