38.Ft OM_uint32
39.Fo gss_process_context_token

44.Sh DESCRIPTION
45Provides a way to pass an asynchronous token to the security service.
46Most context-level tokens are emitted and processed synchronously by
47.Fn gss_init_sec_context
48and
49.Fn gss_accept_sec_context ,
50and the application is informed as to whether further tokens are
51expected by the
52.Dv GSS_C_CONTINUE_NEEDED
53major status bit.
54Occasionally,
55a mechanism may need to emit a context-level token at a point when the
56peer entity is not expecting a token.
57For example,
58the initiator's final call to
59.Fn gss_init_sec_context
60may emit a token and return a status of
61.Dv GSS_S_COMPLETE ,
62but the acceptor's call to
63.Fn gss_accept_sec_context
64may fail.
65The acceptor's mechanism may wish to send a token containing an error
66indication to the initiator,
67but the initiator is not expecting a token at this point,
68believing that the context is fully established.
69.Fn gss_process_context_token
70provides a way to pass such a token to the mechanism at any time.
