gnutls_psk_set_client_credentials_function2 - API function
#include <gnutls/gnutls.h>
void
gnutls_psk_set_client_credentials_function2(gnutls_psk_client_credentials_t
cred, gnutls_psk_client_credentials_function2 * func);
gnutls_psk_client_credentials_t cred
is a gnutls_psk_server_credentials_t type.
gnutls_psk_client_credentials_function2 * func
is the callback function
This function can be used to set a callback to retrieve the
username and password for client PSK authentication. The
callback's function form is: int (*callback)(gnutls_session_t,
gnutls_datum_t* username, gnutls_datum_t* key);
This callback function has the same semantics as that of
gnutls_psk_set_client_credentials_function(), but it allows
non-string usernames to be used.
The username and key ->data must be allocated using
gnutls_malloc(). The username should be an ASCII string or UTF-8
string. In case of a UTF-8 string it is recommended to be
following the PRECIS framework for usernames (rfc8265).
The callback function will be called once per handshake.
The callback function should return 0 on success. -1 indicates an
error.
