22 * @file testbed/testbed_api.h
23 * @brief Interface for functions internally exported from testbed_api.c
24 * @author Sree Harsha Totakura
32 * Enumeration of operations
37 * Peer create operation
42 * Peer start operation
52 * Peer destroy operation
57 * Get peer information operation
62 * Overlay connection operation
75 * Testbed operation structure
77 struct GNUNET_TESTBED_Operation
80 * next pointer for DLL
82 struct GNUNET_TESTBED_Operation *next;
85 * prev pointer for DLL
87 struct GNUNET_TESTBED_Operation *prev;
90 * The controller on which this operation operates
92 struct GNUNET_TESTBED_Controller *controller;
95 * The ID for the operation;
97 uint64_t operation_id;
100 * The type of operation
102 enum OperationType type;
105 * Data specific to OperationType
112 * The message queue for sending messages to the controller service
117 * Structure for a controller link
119 struct ControllerLink;
123 * Enumeration of states of OperationContext
125 enum OperationContextState
128 * The initial state where the associated operation has just been created
129 * and is waiting in the operation queues to be started
134 * The operation has been started. It may occupy some resources which are to
135 * be freed if cancelled.
140 * The operation has finished. The end results of this operation may occupy
141 * some resources which are to be freed by operation_done
148 * Context information for GNUNET_TESTBED_Operation
150 struct OperationContext
155 struct OperationContext *next;
160 struct OperationContext *prev;
163 * The controller to which this operation context belongs to
165 struct GNUNET_TESTBED_Controller *c;
170 struct GNUNET_TESTBED_Operation *op;
173 * Data relevant to the operation
178 * The id of the opearation
183 * The type of operation
185 enum OperationType type;
188 * The state of the operation
190 enum OperationContextState state;
195 * Handle to interact with a GNUnet testbed controller. Each
196 * controller has at least one master handle which is created when the
197 * controller is created; this master handle interacts with the
198 * controller process, destroying it destroys the controller (by
199 * closing stdin of the controller process). Additionally,
200 * controllers can interact with each other (in a P2P fashion); those
201 * links are established via TCP/IP on the controller's service port.
203 struct GNUNET_TESTBED_Controller

209 struct GNUNET_TESTBED_Host *host;
212 * The controller callback
