/* DESCRIPTION */
|
|
/* */
|
|
/* */
|
|
/* 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. */
|
|
/* After pthread_detach() has been issued, it is not valid to try to */
|
|
/* pthread_join() with the target thread. */
|
|
/* Eventually, you should call pthread_join() or pthread_detach() for */
|
|
/* every thread that is created joinable (with a detachstate of */
|
|
/* PTHREAD_CREATE_JOINABLE)so that the system can reclaim all resources*/
|
|
/* associated with the thread. Failure to join to or detach joinable */
|
|
/* threads will result in memory and other resource leaks until the */
|
|
/* process ends. If thread doesn't represent a valid undetached thread,*/
|
|
/* pthread_detach() will return ESRCH. */
