However, this does not seem to work. Each time I create a thread the application's memory footprint grows by 128 bytes and this memory is never released. > > Am I doing this right? > > From man pthread_detach: The *pthread_detach*() function indicates that system resources for the specified /thread/ should be reclaimed when the thread ends. If the thread is already ended, resources are reclaimed immediately. *This routine does not cause the thread to end. *So, unless your 'mythread' routine has successfully completed, the associated resources will not be reclaimed.
