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.
