NAME¶gnutls_idna_map - API function
int gnutls_idna_map(const char * input, unsigned ilen, gnutls_datum_t * out, unsigned flags);
- 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¶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¶GNUTLS_E_INVALID_UTF8_STRING on invalid UTF-8 data, or 0 on success.
