PTHREAD_DETACH(3)					     Library Functions Manual						 PTHREAD_DETACH(3)

NAME
       pthread_detach - put a running thread in the detached state

SYNOPSIS
       #include <pthread.h>

       int pthread_detach(pthread_t th);

DESCRIPTION
       pthread_detach  put the thread th in the detached state. This guarantees that the memory resources consumed by th will be freed immediately
       when th terminates. However, this prevents other threads from synchronizing on the termination of th using pthread_join.

       A thread can be created initially in the detached state, using the detachstate attribute to pthread_create(3).  In contrast, pthread_detach
       applies to threads created in the joinable state, and which need to be put in the detached state later.

       After  pthread_detach  completes,  subsequent  attempts	to  perform pthread_join on th will fail. If another thread is already joining the
       thread th at the time pthread_detach is called, pthread_detach does nothing and leaves th in the joinable state.

RETURN VALUE
       On success, 0 is returned. On error, a non-zero error code is returned.

ERRORS
       ESRCH  No thread could be found corresponding to that specified by th

       EINVAL the thread th is already in the detached state
