NAME        top

       gnutls_psk_set_client_credentials_function2 - API function

SYNOPSIS        top

#include <gnutls/gnutls.h>voidgnutls_psk_set_client_credentials_function2(gnutls_psk_client_credentials_tcred, gnutls_psk_client_credentials_function2 *func);

ARGUMENTS        top

       gnutls_psk_client_credentials_t cred                   is agnutls_psk_server_credentials_ttype.       gnutls_psk_client_credentials_function2 * func                   is the callback function

DESCRIPTION        top

       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 ofgnutls_psk_set_client_credentials_function(), but it allows       non-string usernames to be used.       Theusername andkey ->data must be allocated usinggnutls_malloc().  Theusername 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.
