NAME
gnutls_psk_set_server_credentials_function2 - API function
SYNOPSIS
#include <gnutls/gnutls.h>
void
gnutls_psk_set_server_credentials_function2(3)
cred, gnutls_psk_server_credentials_function2 func);
ARGUMENTS
gnutls_psk_server_credentials_t cred
is a gnutls_psk_server_credentials_t type.
gnutls_psk_server_credentials_function2 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 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.
