gnutls_psk_set_server_credentials_function3 - API function
#include <gnutls/gnutls.h>
void
gnutls_psk_set_server_credentials_function3(gnutls_psk_server_credentials_t
cred, gnutls_psk_server_credentials_function3 func);
gnutls_psk_server_credentials_t cred
is a gnutls_psk_server_credentials_t type.
gnutls_psk_server_credentials_function3 func
is the callback function
This function can be used to set a callback to retrieve the
user's PSK credentials. The callback's function form is: int
(*callback)(gnutls_session_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 associated 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.
