.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].
