SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       void  gnutls_psk_set_server_credentials_function(gnutls_psk_server_cre‐
12       dentials_t cred, gnutls_psk_server_credentials_function * func);
13

ARGUMENTS

15       gnutls_psk_server_credentials_t cred
16                   is a gnutls_psk_server_credentials_t type.
17
18       gnutls_psk_server_credentials_function * func
19                   is the callback function
20

DESCRIPTION

22       This function can be used to set a callback to retrieve the user's  PSK
23       credentials.    The   callback's   function   form   is:   int  (*call‐
24       back)(gnutls_session_t, const char* username, gnutls_datum_t* key);
25
26        username contains the actual username.  The  key must be filled in us‐
27       ing the gnutls_malloc().
28
29       In case the callback returned a negative number then gnutls will assume
30       that the username does not exist.
31
32       The callback function will only be  called  once  per  handshake.   The
33       callback function should return 0 on success, while -1 indicates an er‐
34       ror.
