PTHREAD_ATTR_GETDETACHSTATE(3P) 			     POSIX Programmer's Manual				   PTHREAD_ATTR_GETDETACHSTATE(3P)

PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

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, respectively, shall get and set the detachstate attribute in
       the attr object.

       For pthread_attr_getdetachstate(), detachstate shall be set to either PTHREAD_CREATE_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_setdetachstate() shall return a value of 0; otherwise, an  error
       number shall be returned to indicate 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].

       The following sections are informative.

NAME

       pthread_attr_getdetachstate, pthread_attr_setdetachstate - get or set detachstate attribute

SYNOPSIS

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

       int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);

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

       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_setdetachstate() and pthread_attr_getdetachstate(), respectively, set and  get	the  detachstate  attribute  in  the  attr
       object.

       The  detachstate  can be set to either  PTHREAD_CREATE_DETACHED or  PTHREAD_CREATE_JOINABLE. A value of	PTHREAD_CREATE_DETACHED causes all
       threads created with attr to be in the detached state, whereas using a value of PTHREAD_CREATE_JOINABLE causes  all  threads  created  with
       attr to be in the joinable state. The default value of the detachstate attribute is PTHREAD_CREATE_JOINABLE.

       Upon  successful completion, pthread_attr_setdetachstate() and pthread_attr_getdetachstate() return a value of  0. Otherwise, an error num-
       ber is returned to indicate the error.

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

       The pthread_attr_setdetachstate() or pthread_attr_getdetachstate() functions may fail if:

       EINVAL	       attr or detachstate is invalid.
