PTHREAD_DETACH(3)                                            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
