ARGUMENTS

17       gnutls_psk_client_credentials_t          cred
18                   is a gnutls_psk_server_credentials_t structure.

DESCRIPTION

24       This function can be used to set a callback to  retrieve  the  username
25       and  password  for  client PSK authentication.  The callback's function
26       form   is:   int   (*callback)(gnutls_session_t,    char**    username,
27       gnutls_datum* key);
28
29       The username and key must be allocated using gnutls_malloc().  username
30       should be ASCII strings or UTF-8 strings prepared using the  "SASLprep"
31       profile of "stringprep".
32
33       The callback function will be called once per handshake.
34
35       The  callback  function  should  return  0 on success.  -1 indicates an
36       error.
