| 72 | * @class nua_client_request | |||
| 73 | * | |||
| 74 | * Each handle has a queue of client-side requests; if a request is pending, | |||
| 75 | * a new request from API is added to the queue. After the request is | |||
| 76 | * complete, it is removed from the queue and destroyed by the default. The | |||
| 77 | * exception is the client requests bound to a dialog usage: they are saved | |||
| 78 | * and re-used when the dialog usage is refreshed (and sometimes when the | |||
| 79 | * usage is terminated). | |||
| 80 | * | |||
| 81 | * The client request is subclassed and its behaviour modified using virtual | |||
| 82 | * function table in #nua_client_methods_t. | |||
| 83 | * | |||
| 84 | * The first three methods (crm_template(), crm_init(), crm_send()) are | |||
| 85 | * called when the request is sent first time. | |||
| 86 | * | |||
| 87 | * The crm_template() is called if a template request message is needed (for | |||
| 88 | * example, in case of unregister, unsubscribe and unpublish, the template | |||
| 89 | * message is taken from the request establishing the usage). | |||
| 90 | * | |||
| 91 | * The crm_init() is called when the template message and dialog leg has | |||
| 92 | * been created and populated by the tags procided by the application. Its | |||
| 93 | * parameters msg and sip are pointer to the template request message that | |||
| 94 | * is saved in the nua_client_request::cr_msg field. | |||
| 95 | * | |||
| 96 | * The crm_send() is called with a copy of the template message that has | |||
| 97 | * been populated with all the fields included in the request, including | |||
| 98 | * @CSeq and @MaxForwards. The crm_send() function, such as | |||
| 99 | * nua_publish_client_request(), usually calls nua_base_client_trequest() that | |||
| 100 | * then creates the nta-level transaction. | |||
| 101 | * | |||
| 102 | * The response to the request is processed by crm_check_restart(), which | |||
| 103 | * modifies and restarts the request when needed (e.g., when negotiating | |||
| 104 | * expiration time). After the request has been suitably modified, e.g., the | |||
| 105 | * expiration time has been increased, the restart function calls | |||
| 106 | * nua_client_restart(), which restarts the request and relays the | |||
| 107 | * intermediate response to the application with nua_client_restart() and | |||
| 108 | * crm_report(). | |||
| 109 | * | |||
| 110 | * The final responses are processed by crm_recv() and and preliminary ones | |||
| 111 | * by crm_preliminary(). All virtual functions should call | |||
| 112 | * nua_base_client_response() beside method-specific processing. | |||
| 113 | * | |||
| 114 | * The nua_base_client_response() relays the response to the application with | |||
| 115 | * nua_client_restart() and crm_report(). | |||
| 116 | * | |||
| 117 | * @par Terminating Dialog Usages and Dialogs | |||
| 118 | * | |||
| 119 | * The response is marked as terminating with nua_client_set_terminating(). | |||
| 120 | * When a terminating request completes the dialog usage is removed and the | |||
| 121 | * dialog is destroyed (unless there is an another active usage). | |||
