gnutls_psk_set...tials_function3(3) gnutls gnutls_psk_set...tials_function3(3) NAME gnutls_psk_set_client_credentials_function3 - API function SYNOPSIS #include <gnutls/gnutls.h> void gnutls_psk_set_client_credentials_function3(gnutls_psk_client_creden- tials_t cred, gnutls_psk_client_credentials_function3 * func); ARGUMENTS gnutls_psk_client_credentials_t cred is a gnutls_psk_server_credentials_t type. gnutls_psk_client_credentials_function3 * 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, gnutls_datum_t* context, gnutls_psk_key_flags *flags); This callback function has the same semantics as that of gnutls_psk_set_client_credentials_function2(), but it returns flags associ- ated with the key. The callback may import external PSK using the method described in RFC 9258 by using gnutls_psk_format_imported_identity(). The data field of username , key , and context 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. REPORTING BUGS Report bugs to <bugs@gnutls.org>.
