gnutls_psk_set_server_credentials_function - API function


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


gnutls_psk_server_credentials_t cred is a gnutls_psk_server_credentials_t type. gnutls_psk_server_credentials_function * 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 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.
