.SH NAME
pthread_attr_getdetachstate, pthread_attr_setdetachstate \- get and
set the detachstate attribute
.SH SYNOPSIS
.LP
\fB#include <pthread.h>
.br
.sp
int pthread_attr_getdetachstate(const pthread_attr_t *\fP\fIattr\fP\fB,
.br
\ \ \ \ \ \ int *\fP\fIdetachstate\fP\fB);

int pthread_attr_setdetachstate(pthread_attr_t *\fP\fIattr\fP\fB,
int\fP \fIdetachstate\fP\fB); \fP

\fP
.SH DESCRIPTION
.LP
The \fIdetachstate\fP 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 \fIpthread_detach\fP()
or \fIpthread_join\fP() function is an error.
.LP
The \fIpthread_attr_getdetachstate\fP() and \fIpthread_attr_setdetachstate\fP()
functions, respectively, shall get and set the
\fIdetachstate\fP attribute in the \fIattr\fP object.
.LP
For \fIpthread_attr_getdetachstate\fP(), \fIdetachstate\fP shall be
set to either PTHREAD_CREATE_DETACHED or
PTHREAD_CREATE_JOINABLE.
.LP
For \fIpthread_attr_setdetachstate\fP(), the application shall set
\fIdetachstate\fP to either PTHREAD_CREATE_DETACHED or
PTHREAD_CREATE_JOINABLE.
.LP
A value of PTHREAD_CREATE_DETACHED shall cause all threads created
with \fIattr\fP to be in the detached state, whereas using a
value of PTHREAD_CREATE_JOINABLE shall cause all threads created with
\fIattr\fP to be in the joinable state. The default value of
the \fIdetachstate\fP attribute shall be PTHREAD_CREATE_JOINABLE.
.SH RETURN VALUE
.LP
Upon successful completion, \fIpthread_attr_getdetachstate\fP() and
\fIpthread_attr_setdetachstate\fP() shall return a value
of 0; otherwise, an error number shall be returned to indicate the
error.
.LP
The \fIpthread_attr_getdetachstate\fP() function stores the value
of the \fIdetachstate\fP attribute in \fIdetachstate\fP if
successful.
.SH ERRORS
.LP
The \fIpthread_attr_setdetachstate\fP() function shall fail if:
.TP 7
.B EINVAL
The value of \fIdetachstate\fP was not valid
.sp
.LP
These functions shall not return an error code of [EINTR].
