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.
