pthread_detach

pthread_detach(3C)														pthread_detach(3C)

NAME

       pthread_detach - detach a thread

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_detach(pthread_t thread);

       The  pthread_detach()  function	is  used  to  indicate to the implementation that storage for the thread thread can be reclaimed when that
       thread terminates. In other words,   pthread_detach()  dynamically  resets  the	 detachstate  attribute  of  the  thread  to  PTHREAD_CRE-
       ATE_DETACHED.  After  a	successful  call  to  this  function,  it  would not be necessary to reclaim the thread using  pthread_join(). See
       pthread_join(3C). If thread has not terminated, pthread_detach() will not cause it to terminate. The effect  of	multiple  pthread_detach()
       calls on the same target thread is unspecified.

       If successful, pthread_detach() returns	0. Otherwise, an error number is returned to indicate the error.

       The  pthread_detach() function will fail if:

       EINVAL	       The implementation has detected that the value specified by thread does not refer to a joinable thread.

       ESRCH	       No thread could be found corresponding to that specified by the given thread  ID.
