Name

gnutls_psk_set_server_credentials_function — Used to set a callback to retrieve the user's PSK credentials

Synopsis

#include <gnutls/gnutls.h>
void gnutls_psk_set_server_credentials_function( gnutls_psk_server_credentials_t   cred,
  gnutls_psk_server_credentials_function *   func);

ARGUMENTS

gnutls_psk_server_credentials_t cred

is a gnutls_psk_server_credentials_t structure.

gnutls_psk_server_credentials_function * func

is the callback function

DESCRIPTION

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 char* username, gnutls_datum_t* key);

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.
