pthread_detach


SYNOPSIS
       #include <pthread.h>

       int pthread_detach(pthread_t thread);

       Compile and link with -pthread.

DESCRIPTION
       The  pthread_detach() function marks the thread identified by thread as
       detached.  When a detached thread terminates, its resources  are  auto-
       matically  released  back  to  the  system without the need for another
       thread to join with the terminated thread.

       Attempting to detach an already detached thread results in  unspecified
       behavior.

RETURN VALUE
       On  success,  pthread_detach() returns 0; on error, it returns an error
       number.

ERRORS
       EINVAL thread is not a joinable thread.

       ESRCH  No thread with the ID thread could be found.

CONFORMING TO
       POSIX.1-2001.

NOTES
       Once  a  thread  has  been  detached,   it   can't   be   joined   with
       pthread_join(3) or be made joinable again.

       A new thread can be created in a detached state using pthread_attr_set-
       detachstate(3) to set the detached attribute of the  attr  argument  of
       pthread_create(3).

       The  detached  attribute  merely  determines the behavior of the system
       when the thread terminates; it does not prevent the thread  from  being
       terminated if the process terminates using exit(3) (or equivalently, if
       the main thread returns).

       Either pthread_join(3) or pthread_detach() should be  called  for  each
       thread  that  an  application creates, so that system resources for the
       thread can be released.  (But note that the resources  of  all  threads
       are freed when the process terminates.)

EXAMPLE
       The following statement detaches the calling thread:

           pthread_detach(pthread_self());
