gnutls_psk_set...tials_function3(3) gnutls gnutls_psk_set...tials_function3(3) NAME gnutls_psk_set_server_credentials_function3 - API function SYNOPSIS #include <gnutls/gnutls.h> void gnutls_psk_set_server_credentials_function3(gnutls_psk_server_creden- tials_t cred, gnutls_psk_server_credentials_function3 func); ARGUMENTS gnutls_psk_server_credentials_t cred is a gnutls_psk_server_credentials_t type. gnutls_psk_server_credentials_function3 func is the callback function DESCRIPTION This function can be used to set a callback to retrieve the user's PSK cre- dentials. The callback's function form is: int (*callback)(gnutls_ses- sion_t, const gnutls_datum_t* username, gnutls_datum_t* key, gnutls_psk_key_flags *flags); This callback function has the same semantics as that of gnutls_psk_set_server_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(). username contains the actual username. The key must be filled in using the gnutls_malloc(). In case the callback returned a negative number then gnutls will assume that the username does not exist. The callback function will only be called once per handshake. The callback function should return 0 on success, while -1 indicates an error. REPORTING BUGS Report bugs to <bugs@gnutls.org>.
