PTHREAD_ATTR_GETDETACHSTATE(P)	    POSIX Programmer's Manual	   PTHREAD_ATTR_GETDETACHSTATE(P)

NAME
       pthread_attr_getdetachstate,  pthread_attr_setdetachstate  -  get  and set the detachstate
       attribute

SYNOPSIS
       #include <pthread.h>

       int pthread_attr_getdetachstate(const pthread_attr_t *attr,
	      int *detachstate);
       int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);

DESCRIPTION
       The detachstate attribute controls whether the thread is created in a detached  state.  If
       the  thread  is	created  detached,  then use of the ID of the newly created thread by the
       pthread_detach() or pthread_join() function is an error.

       The pthread_attr_getdetachstate()  and  pthread_attr_setdetachstate()  functions,  respec-
       tively, shall get and set the detachstate attribute in the attr object.

       For  pthread_attr_getdetachstate(),  detachstate  shall	be  set  to  either  PTHREAD_CRE-
       ATE_DETACHED or PTHREAD_CREATE_JOINABLE.

       For  pthread_attr_setdetachstate(),  the  application  shall  set  detachstate  to  either
       PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.

       A  value of PTHREAD_CREATE_DETACHED shall cause all threads created with attr to be in the
       detached state, whereas using a value of PTHREAD_CREATE_JOINABLE shall cause  all  threads
       created	with  attr  to	be  in	the  joinable state. The default value of the detachstate
       attribute shall be PTHREAD_CREATE_JOINABLE.

RETURN VALUE
       Upon  successful  completion,  pthread_attr_getdetachstate()  and  pthread_attr_setdetach-
       state()	shall  return a value of 0; otherwise, an error number shall be returned to indi-
       cate the error.

       The pthread_attr_getdetachstate() function stores the value of the  detachstate	attribute
       in detachstate if successful.

ERRORS
       The pthread_attr_setdetachstate() function shall fail if:

       EINVAL The value of detachstate was not valid

       These functions shall not return an error code of [EINTR].
