NAME

12       pthread_attr_getdetachstate, pthread_attr_setdetachstate - get and  set
13       the detachstate attribute
14

SYNOPSIS

16       #include <pthread.h>
17
18       int pthread_attr_getdetachstate(const pthread_attr_t *attr,
19              int *detachstate);
20       int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);

DESCRIPTION

24       The  detachstate  attribute controls whether the thread is created in a
25       detached state. If the thread is created detached, then use of  the  ID
26       of  the  newly created thread by the pthread_detach() or pthread_join()
27       function is an error.
28
29       The  pthread_attr_getdetachstate()  and   pthread_attr_setdetachstate()
30       functions, respectively, shall get and set the detachstate attribute in
31       the attr object.
32
33       For pthread_attr_getdetachstate(), detachstate shall be set  to  either
34       PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.
35
36       For  pthread_attr_setdetachstate(),  the  application shall set detach‐
37       state to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.
38
39       A value of PTHREAD_CREATE_DETACHED shall cause all threads created with
40       attr to be in the detached state, whereas using a value of PTHREAD_CRE‐
41       ATE_JOINABLE shall cause all threads created with attr  to  be  in  the
42       joinable state. The default value of the detachstate attribute shall be
43       PTHREAD_CREATE_JOINABLE.
44

RETURN VALUE

46       Upon   successful   completion,    pthread_attr_getdetachstate()    and
47       pthread_attr_setdetachstate()  shall return a value of 0; otherwise, an
48       error number shall be returned to indicate the error.
49
50       The pthread_attr_getdetachstate() function  stores  the  value  of  the
51       detachstate attribute in detachstate if successful.
52

ERRORS

54       The pthread_attr_setdetachstate() function shall fail if:
55
56       EINVAL The value of detachstate was not valid
57
58
59       These functions shall not return an error code of [EINTR].
