gss_process_context_token -- Pass a security context to the security service 

C Prototype 

OM_uint32 gss_process_context_token(
      OM_uint32                minor_status,
      gss_ctx_id_t             context_handle,
      gss_buffer_t             token_buffer ); 

Arguments 

minor_status (output)		An implementation-specific status code.
context_handle (input)		The context handle of the context on which the token is to be processed.
token_buffer (input)		A pointer to the token to process.

Description 

This routine provides a way to pass an asynchronous token to the security service. Most context-level tokens are emitted and processed synchronously by gss_init_sec_context and gss_accept_sec_context, and the application is informed as to whether further tokens are expected by the GSS_C_CONTINUE_NEEDED status return. Occasionally, a mechanism may need to emit a context-level token at a point when the peer entity is not expecting a token. For example, the initiator's final call to gss_init_sec_context may emit a token and return a status of GSS_S_COMPLETE, but the acceptor's call to gss_accept_sec_context may fail. The acceptor's mechanism may wish to send a token containing an error indication to the initiator, but the initiator is not expecting a token at this point, believing that the context is fully established. The gss_process_context_token routine provides a way to pass such a token to the mechanism at any time.

Return Values 

This routine returns one of the following GSS status codes:

GSS_S_COMPLETE	Successful completion.
GSS_S_DEFECTIVE_TOKEN	Indicates that consistency checks performed on the token failed.
GSS_S_FAILURE	Failure. See minor_status for more information.
GSS_S_NO_CONTEXT	The context_handle did not refer to a valid context.
