gnutls_idna_map(3) gnutls gnutls_idna_map(3)
gnutls_idna_map - API function
#include <gnutls/gnutls.h>
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
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.
GNUTLS_E_INVALID_UTF8_STRING on invalid UTF-8 data, or 0 on
success.
