PJSUA initialization and shutdown
To use PJSIP, it is recommended to call pj_init() and pj_shutdown() from the main thread. After pj_init() is completed, application can continue with the initialization or create a secondary/worker thread and register the thread by calling pj_thread_register(). As described in PJSUA-API Basic API documentation, app needs to call pjsua_create(), pjsua_pool_create(), pjsua_init() to perform the initialization. Then app must call pjsua_start() to start PJSUA and finally after everything is done, call pjsua_destroy() to shut it down. Sample code:
int main() { pj_init(); // Continue with PJSUA initialization here or create a secondary thread .... // After pjsua_destroy() is called pj_shutdown(); } int worker_thread() { // Register the thread, after pj_init() is called pj_thread_register(); // Create pjsua and pool pjsua_create(); pjsua_pool_create(); // Init pjsua pjsua_init(); // Start pjsua pjsua_start(); ......... // Destroy pjsua pjsua_destroy(); }
When restarting the library, after pjsua_destroy() is completed, application needs to call pj_shutdown() and pj_init() in the main thread. Application also needs to make sure that the number of calls to pj_shutdown() matches with the calls to pj_init()
