NAME

6       pthread_attr_getdetachstate,  pthread_attr_setdetachstate - get and set
7       the detachstate attribute
8

SYNOPSIS

10       #include <pthread.h>
11
12       int pthread_attr_getdetachstate(const pthread_attr_t *attr,
13              int *detachstate);
14       int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);

DESCRIPTION

18       The detachstate attribute controls whether the thread is created  in  a
19       detached  state.  If the thread is created detached, then use of the ID
20       of the newly created thread by the pthread_detach()  or  pthread_join()
21       function is an error.
22
23       The   pthread_attr_getdetachstate()  and  pthread_attr_setdetachstate()
24       functions, respectively, shall get and set the detachstate attribute in
25       the attr object.
26
27       For  pthread_attr_getdetachstate(),  detachstate shall be set to either
28       PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.
29
30       For pthread_attr_setdetachstate(), the application  shall  set  detach‐
31       state to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.
32
33       A value of PTHREAD_CREATE_DETACHED shall cause all threads created with
34       attr to be in the detached state, whereas using a value of PTHREAD_CRE‐
35       ATE_JOINABLE  shall  cause  all  threads created with attr to be in the
36       joinable state. The default value of the detachstate attribute shall be
37       PTHREAD_CREATE_JOINABLE.
38

RETURN VALUE

40       Upon    successful    completion,   pthread_attr_getdetachstate()   and
41       pthread_attr_setdetachstate() shall return a value of 0; otherwise,  an
42       error number shall be returned to indicate the error.
43
44       The  pthread_attr_getdetachstate()  function  stores  the  value of the
45       detachstate attribute in detachstate if successful.
46

ERRORS

48       The pthread_attr_setdetachstate() function shall fail if:
49
50       EINVAL The value of detachstate was not valid
51
52
53       These functions shall not return an error code of [EINTR].
