NAME
       gnutls_psk_set_client_credentials_function2 - API function


SYNOPSIS
       #include <gnutls/gnutls.h>

       void           gnutls_psk_set_client_credentials_function2(gnutls_psk_client_credentials_t          cred,
       gnutls_psk_client_credentials_function2 * func);


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


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.
