Функции API (API function)

Имя (Name)

gnutls_psk_set_client_credentials_function2 - API function

Синопсис (Synopsis)

#include <gnutls/gnutls.h>

void gnutls_psk_set_client_credentials_function2(gnutls_psk_client_credentials_t cred, gnutls_psk_client_credentials_function2 * func);


Аргументы (Arguments)

gnutls_psk_client_credentials_t cred
                   is a gnutls_psk_server_credentials_t type.

gnutls_psk_client_credentials_function2 * func is the callback function


Описание (Description)

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.
