gnutls_psk_set_server_credentials_function2 - API function
#include <gnutls/gnutls.h> void gnutls_psk_set_server_credentials_function2(gnutls_psk_server_credentials_t cred, gnutls_psk_server_credentials_function2 func);
gnutls_psk_server_credentials_t cred is a gnutls_psk_server_credentials_t type. gnutls_psk_server_credentials_function2 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); This callback function has the same semantics as that of gnutls_psk_set_server_credentials_function(), but it allows non-string usernames to be used. 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.
