25 this defines the structures associated with "composite"
26 requests. Composite requests are libcli requests that are internally
27 implemented as multiple async calls, but can be treated as a
28 single call via these composite calls. The composite calls are
29 particularly designed to be used in async applications.
30 you can also stack multiple level of composite call
34 a composite call moves between the following 3 states.
36 enum composite_state { COMPOSITE_STATE_INIT, /* we are creating the request */
37 COMPOSITE_STATE_IN_PROGRESS, /* the request is in the outgoing socket Q */
38 COMPOSITE_STATE_DONE, /* the request is received by the caller finished */
39 COMPOSITE_STATE_ERROR }; /* a packet or transport level error has occurred */
41 /* the context of one "composite" call */
42 struct composite_context {
43 /* the external state - will be queried by the caller */
44 enum composite_state state;
46 /* a private pointer for use by the composite function
50 /* status code when finished */
53 /* the event context we are using */
54 struct event_context *event_ctx;
56 /* information on what to do on completion */
58 void (*fn)(struct composite_context *);
66 struct smbcli_request;
69 struct nbt_name_request;
