POpthreads - Stop the current execution of threads and restart them after a specific event
text
Body
copied!<p>I am doing a project on VoIP and I have got pthreads in my C code. I need to start the pthreads and make them work with some sleep in between them. Right now my threads are running and when I get a session end from the server I need to stop the running threads and restart them again new from the beginning. </p> <p>My code looks something like this:</p> <pre><code>void *recv_thread(void *arg) { /*receive the multimedia data and close the recv_thread when there is no more data to receive*/ } void *send_thread(void *arg) { /*send the multimedia data*/ } send_recv_data() { pthread_create(thread2, NULL, send_thread, NULL); pthread_create(thread3, NULL, recv_thread, NULL); } void *first_thread(void *arg) { /*if some condition met the start the routine for creation of two threads one for receiving and one for sending data*/ if(cond == TRUE){ send_recv_data(); } } main() { pthread_create(thread1, NULL, first_thread, NULL); } </code></pre> <p>My question is that once I receive a message from the other user agent that it is sending me no more data then I need to stop both the send and recv threads and then finally first_thread which is responsible for the creation of the other two threads. Once i stop all the threads I need to restart them again. I tried using mutexes and conditional variables but all went in vain.</p> <p>Any idea of how I can overcome this, may be a small piece of simple code would be much more helpful</p> <p>Thanks </p>
